Back in the late nineties Mark Twights forward thinking volume ‘Extreme Alpinism’ hit the shelves. Among his many ideas was the concept of over layering for extra warmth. Prior to this innovative idea the general plan for adding a layer was to remove your gloves, loosen your harness, remove your shell, put on your extra warm layer, shell back on etc, a real faff.
Twights' simple idea was to layer a synthetic insulated jacket over your shell when you needed to boost the warmth of your clothing system. Unlike down, synthetic insulation retains a lot of its thermal properties when wet meaning it doesn’t need protecting from the elements. Fast forward to the current day and the concept of a belay jacket has spread across the worlds mountains and in particular to the demanding world of Scottish winter climbing.
Rab® were one of the first brands to produce a dedicated belay jacket and my original is still going strong after years of abuse. It has a lot of ‘character’ now but fundamentally it still does an amazing job of keeping me warm when the environment is determined to make me wet, cold and miserable.
There are two fields of thought in belay jacket design. One is to go as lightweight as possible with minimal features. It’s all about lightweight maximal warmth for belaying or emergency situations.
The second option is to build a robust technical jacket with plenty of features. This gives the user more survivability and also allows the garment to be used for climbing when conditions are really bad. The latest incarnation from Rab falls into the latter category. The Photon X Jacket is a great looking technical jacket packed full of features - multiple big pockets, reinforced patches, reflective detail, stiffened hood visor and plenty of warmth.
In the last 6 months I’ve worn it to the summit of Antarctica’s Mount Vinson, photographing Emperor penguins on the Weddell Sea, running film safety on a Lake District hillside and on a diverse range of Scottish winter mountain days. Early season conditions in Scotland have been challenging and perfect for hypothermia with the freezing level up around the summits. It’s a bit of a standing joke that the community of mountaineering instructors who work the Scottish winter season measure how bad the weather has been by the number of pairs of gloves they get through in a day. Needless to say there have been a number of 6 glove days in 2017. However, I’ve been very comfortable in the depths of my Photon X. In the worst of conditions it’s great to be able to sink down into the insulated collar and try to hide. The hood goes up and stays up with minimal adjustment and the pockets will swallow a whole picnic of supplies.
The level of insulation is just about perfect for Scottish winter climbing. I’ve warmed up quickly whenever I’ve over layered with it, but interestingly I’ve never felt like overheating when navigating off in a hoolie. It even dries overnight in my unheated campervan so it’s ready to go in the morning, even if I’m not!
Overall a very impressive piece of kit for Scotland and further afield. Bad weather is very much part of the mountaineering game but this is a very useful tool in successfully operating in it.
Synthetic duvet jackets have been a mainstay of my clothing system since becoming a realistic alternative to fleece back in the late nineties. I've used and abused a number of jackets from ultra-lightweight pieces to full expedition parkers and even insulated trousers in polar regions.I’ve found that Primaloft clothing offers a lot of protection and survivability for their weight. They are wind and weatherproof but also keep you warm when wet, which is essential for our typical UK weather.
The latest incarnation of the Xenon-X Jacket had a baptism of fire last month. I teamed it up with the lightweight Vapour Rise Jacket for the variety of different days inherent in being a mountain instructor - from chilly belays while guiding on a Lake District mountain crag, to a soggy day taking photos of a mountain event. It’s been used as a lightweight warm layer for a very windy mountain marathon and as a stunning bivi, high above Chamonix while introducing friends to the delights of alpine climbing. It provided instant warmth after an open water swim under a full moon and spent several days stuffed into the bottom of my rucksack as an emergency layer while instructing.
The new Primaloft Gold Active is slightly less warm weight for weight than its predecessor but it’s more robust matted composition means that the jackets lining fabric can have a more open weave and therefore greater breathability. This becomes very obvious the first time you work up a sweat. Normally I'd be venting a synthetic jacket and removing hats and gloves to avoid overheating, but the Xenon-X was comfortable across a wider range of activity, quickly wicking moisture and heat away, which also meant I didn't get cold and clammy when I stopped moving. Despite its low weight it feels reassuringly warm and will easily layer over or under my shell.
Rab® have kept it simple with a couple of hand-warmer pockets and an internal chest pocket which will take a map or guidebook with ease, while the under helmet hood is extremely comfortable and useful.
Many lightweight fabrics are prone to getting jammed in zips, however with the Xenon-X the wind baffle behind the teeth has been slightly stiffened providing the perfect balance between zip jam prevention and minimal weight and bulk.
Practical as a summer and winter climbing layer, this jacket is becoming my go to option for UK instruction and guiding. It ticks all of the boxes that a lightweight synthetic jacket should but introduces an element of flexibility. I look forward to putting the Xenon-X through it’s paces in Antarctica at the end of this year. I’ll report back on how it holds up!
I've just returned from seven weeks in Nepal climbing and guiding. My personal highlight was a solo of the South West Ridge of Ama Dablam, summiting in seven hours after an open bivi at camp two. Either side of this I lead two very successful commercial trips to Island Peak in the Khumbu and Thapu Chuli or Tent Peak in the Annapurna Sanctuary. The North Face very kindly kitted me out with three items from their flagship Meru range - the Shaffle down jacket, the Meru mitts and the Gore Tex shell of the same name. I wrote a couple of initial reviews for the Shaffle & Meru jackets just before I departed but have now had a chance to put them through their paces in the environment they were designed for.
I opted to use a similar system to The North Face athlete Andy Houseman, as described to UKC, with a technical baselayer, synthetic insulated jacket, Meru Gore shell and the Shaffle as a belay jacket. The Khumbu was experiencing it's coldest October in twenty years with plenty of high winds so I spent a lot of time climbing in the full system. Summit temperatures on Island Peak were -26oC with strong winds.
My last few trips to the Himalaya I've gone for the soft shell option only taking a very lightweight waterproof for the walk in. However based on my experiences in the Lakes I decided to use the Meru jacket in my system. The Gore Active fabric proved to be incredibly breathable and I didn't suffer any condensation problems.
I usually take a size large but the medium gave me a good neat fit. I would have struggled to get any more insulation underneath but as part of an over layering system it worked very well. I really appreciated the slightly longer length which was a welcome boost to my comfort levels in the high winds. Combined with the longer length of the Shaffle jacket and boots with built in gaiters I was able to use a relatively lightweight soft shell trouser in all but the coldest conditions.
In my initial review of the jacket I was critical of the inclusion of mesh backed chest pockets. These were designed to increase ventilation in the same way as pit zips arguably do. I personally feel that your shell should be as simple and bombproof as possible. Using these pockets in poor conditions means your core will very quickly become wet and cold. Additionally you can only use this venting if you have nothing in the pockets. In practice I never used the pockets to cool down preferring to use them to store hat and gloves which I found far more effective at adjusting my temperature.
The hood is by far the best non wired design I've used being one of the few that is truly helmet compatible. it won't clinch down to a full tunnel but does provide plenty of protection from the side. It's major advantage is that it will stay in place over a helmet or hat and turns with the head with the volume reducer being a particularly efficient design. I'm not usually a huge fan of hoods finding them restrictive in all but the worst weather but in the windy conditions experienced this season I found myself tucked away under this hood for most of the time at altitude.
The jacket is made up of two different weights of fabric to help protect wear points and increase durability. It proved itself as a tough jacket standing up to almost everything I threw at it apart from minor damage to the front / chest pockets. This area is made of the lighter weight fabric with no reinforcing however I find that it is always prone to damage if you have anything in the pockets. Maybe it's my graceful climbing style or just the fact that I store a lot of equipment in the pockets but it does always seem very vulnerable and my last four waterproof jackets have all suffered from this.
The rubberised dots around the shoulders and waist seemed to work. I wasn't carrying a huge rack but I didn't notice my harness slipping and I certainly didn't have to re-tighten it at any point during the day. A number of other manufacturers have tried similar ideas but have had real problems with durability but I'm happy to report that all dots are still in place! The velcro cuffs were a fairly universal design but with a better than average contact area. I've had real problems with small velcro tabs becoming choked in heavy snow conditions meaning it's impossible to seal the cuff. All jackets suffer from this to some extent but I anticipate this not being a huge problem with the Meru.
The best compliment that I can pay this jacket is that I didn't notice it in action. It provided a simple windproof, waterproof and breathable shell in which I could climb and trek. The features all worked and there was minimal faff. Some reinforcing on the front of the jacket and waterproof pockets and this jacket would nearly be perfect.
SHAFFLE DOWN JACKET
This jacket proved to be incredibly lightweight, useful and a great colour!. It uses 200grams of top quality down in a jacket that weights just 808grams. With no velcro on the cuffs it was very easy to whip on and off and I found myself using it for even short breaks or even in anticipation of windy conditions on the col above.
Like the Meru Gore jacket I wore a medium rather than my normal large which comfortably fitted over my three under layers. The very lightweight face fabric has proved surprisingly tough and there's no visible damage. Overall it's a very simple design with no drawcords, velcro, excess pockets etc, yet it maximises it's insulation while keeping the weight right down.
Sat around in the mess tent at base camp I had to use a couple of other layers plus this jacket to be comfortable. My older and far heavier expedition weight jacket is usually fine just over a thermal but now feels like overkill for anything under 7000m. It certainly takes up a lot more space in my bag. I didn't notice any difference in insulation with the body mapping, which places more down in certain areas, but then again I didn't suffer any cold spots in what is essential a very lightweight jacket. The theory behind mapping makes sense and allows The North Face to make the jacket lighter while offering the same level of overall warmth.
The cuffs of this jacket feature a recessed seam which produces a very warm collar of down around the wrist. In practice I couldn't decide if I liked this feature or not. It was certainly very warm giving a real boost to this vulnerable area, (warm wrists mean warm hands) but I found that it kept getting in the way and got very dirty especially when trying to eat dehydrated rations.
The hood worked great fitting over all my other layers and a helmet. It offers limited protection to the face but even without a volume reducer or drawcords it doesn't get in the way even when worn on its own.
The Shaffle is a very striking looking jacket and there were plenty of questions about it. Warmth for weight it's arguably one of the best pieces on the market. The North Face have done a great job at keeping it simple offering maximum warmth with minimal faff.
The Meru Mitts proved to be a very adaptable design being less bulky than traditional high altitude mitts. The combination of pile and Primaloft meant that they were plenty warm enough and were less prone to compression when trying to do anything with them on, a problem with down mitts. With wristovers and thermal gloves I'd be very happy to use these above 8000m with a pair of down mitts in my bag as backup.
I would suggest that the majority of climbs over 6000m these days are made on fixed lines requiring wearers to spend long periods maneuvering a handled Jumar. None of the popular models of ascendor will accept a full down mitt into the handle but the tapered shape of these mitts meant that they worked reasonably well with a Petzl handled version. However the little finger was then vunerable to the cold where it presses against the angle. The Meru mitt has what feels like a stitched through seam in the insulation along it's lower edge which gave a noticeable cold spot in use. I would imagine technical climbing with modern tools would have the same problem. Moving the seam would immediately resolve this problem or a more radical approach would be to fit a foam insert to protect and support this vulnerable spot for the many hours spent hanging from a jumar or ice tool.
The information that came with the mitts described a removable liner. My version didn't have this feature and was the poorer for it. Being able to remove the insulation to aid drying the glove is critical for multi day trips.
The gauntlet style offered plenty of protection without being too bulky over the Shaffle down jacket. There is reduced insulation in the extended cuff to help with this. However the supplied wrist loops are attached to the end of this gauntlet sitting half way up the forearm and proved very fiddly to use restricting removal of the mitt. Despite insisting all my clients used idiot loops on their gloves I was eventually forced to remove mine.
The leather palm has proved very durable and doesn't show any sign of the many meters of fixed line I slid down with an arm wrap - unlike one of my jackets!
I found the fit to be pretty good. I usually take a large glove to get the volume right but this usually leaves my stubby little fingers with rather too much deadspace. In mitts this can be worse but the pre-curved shape and the X-Trafit insert technology seemed to do a very good job of putting my hand in the right position with no excess fabric or insulation getting in the way of the job in hand. Surprisingly for a mitt i was able to operate my ascender and various karabiners while wearing them. The one minor gripe is the fit of the thumb which I found short and snug especially when wearing a pair of thermal gloves.
Overall the fit and technology behind this mitt are very good. A removable inner would transform it into a very practical option for all but the worst conditions.
A great wee film from Andy Houseman in his The North Face Meru kit climbing the Slovak Direct on Denali
For the last few weeks I've been testing a new jacket from The North Face, the innovative Alpine Project Wind Jacket and after a dubious start it's really grown on me. At first glance I struggled to identify where it would fit in to my clothing system. Was it a soft shell, an insulated jacket without the insulation or a heavy weight windproof. The best description is probably all of the above as it's one of those pieces of kit that just seems to work. I must admit I've been using this jacket for a number of activities that probably exceed what the designers had in mind for it but layered over a thin thermal it's kept me comfortable fell running, bouldering, mountain biking, climbing, scrambling, hill walking, road biking, marshaling on a mountain challenge and even a photo shoot for Trail Running magazine.
'Rage against the wind in The North Face Men’s Alpine Project Wind Jacket a new pull-over anorak styled, hooded nylon micro ripstop mountain shell. Coated with a DWR water shedding finish. This wind shell has map accommodating twin alpine pockets and a chest pocket that’s handy for a compass, phone or gps device. The hood adjusts at the back. Simple and rugged ,The Men’s Alpine Project Wind Jacket offers effective wind shell performance as one would expect from a technical, athlete test Summit Series™ jacket.'
Designed as a technical and durable windproof it has proved surprisingly waterproof when caught out by yet another shower at the start of our traditional Lakeland summer. I would still carry a lightweight waterproof with a bad forecast but generally I've been very happy to use this as my shell. The double layer of ripstop nylon has proved very successful at blocking everything the elements can throw at me. There is an extra layer of insulation over the torso provided by an internal thin fleece scrim. However this doesn't extend down the arms which means the jacket doesn't bind when you're trying to put it on over a damp thermal, a great design feature which really makes a practical difference on the hill.
The jackets hood is one of its best features. It's a great fit, feeling comfortable, unrestrictive and turns with your head but offers far more protection than many other wind proofs. The slightly stiffened peak sits just in the right place to deflect the worst of the weather but doesn't restrict your vision. The only adjustment on the whole jacket is a cord at the back that clinches the hood in snug to your head. This also means there are no toggles to whip you in the face. However the price you pay for such a well fitting hood is that it won't fit over a climbing helmet.
Having raved about the hood there are however a couple of significant niggles. There is no way to secure the hood when it’s not in use which means it flaps around in a very annoying manner. Then if you place anything in the chest pocket while the front zip is open then there is a tendency for the hood to be pulled around to the left ending up perched on your shoulder. A simple Velcro strap would transform this jacket for faster paced activities. The second hood issue occurs only with a following wind when the drumming of the fabric over your ears drowns out any other sound (rockfall, climbing partners etc). I suspect this is due to the lightness of the nylon fabric and or the lack of hood adjustment but for whatever reason this is probably the biggest weakness of the jacket. Some reinforcing over the ears or an adjustable draw cord may go some way to helping prevent this?
The rest of the jacket gives a very roomy and comfortable fit. There were plenty of venting options with a long front zip and the lycra bound cuffs could easily be pulled up to your elbows. I get the feeling it would have been brilliant for last months ski touring trip to the Vanoise. The extra water repellancy would have been ideal for my frequent crashes!
Tunnel pockets used to be very popular in outdoor clothing but have pretty much disappeared from use. Here they work extremely well giving loads of room which is accessible while wearing a harness and having a deep lip to help prevent items from escaping if you forget to zip the pocket up. The chest pocket is small but will take a smart phone or compass.
For me this jacket makes a great multipitch cragging top offering lightweight insulation and weatherproofing. A couple of sessions on the very rough gabbro of the Carrick Fell boulders has failed to inflict any damage on the surprisingly tough lightweight fabrics. The jacket is designed to stuff into it's own pocket however one minor design flaw is the lack of an internal loop for attaching it to the back of your climbing harness.
After my initial confusion I think this jacket has identified it's niche offering a weather resistant shell that's just that bit more practical for UK conditions than a traditional soft shell and compliments my existing system of thermals, Primaloft insulation and hard shell waterproofs. A wee bit of fine tuning and this could become a classic multi activity jacket.
