12 years in the making, our fully waterproof and breathable Definition Jacket is engineered to cope with whatever you, the mountains, and the weather can throw at it.
'The Definition is arguably as good or better than some jackets costing twice as much. The cut is sleek and efficient, components are top-notch – we love the glove-friendly embedded Cohaesive cord-grips – and the unbranded fabric works well and feels reassuringly tough. The effective helmet-compatible hood means you can use it for anything from full-on mountaineering to general hill-walking' Outdoors Magic
The Definition jacket is a fortress, it is designed to face the foulest, wettest, windiest, snowiest, wildest weather. Fully featured and tough as old boots, this is the jacket that will take whatever abuse you want to throw at it, from Scottish winter, alpine climbing to Munro bagging.
Definition is breathable and waterproof. Its face fabric and backer are manufactured from tough nylon for superb durability. Sandwiched between these is a waterproof / breathable PU/PTFE membrane; the result is the best combination of durability and breathability available in heavier weight 3 layer fabric. It is our most durable jacket yet.
Fit for purpose doesn’t just mean waterproof - it has to fit you! Definition is designed to sit over your other layers, its cut is tuned so that it does not ride up to expose your back or tum when you swing your axes above your head. The hood is large enough to fit over a climbing helmet and deflect spindrift from engulfing your core.
The mountains are a changeable environment and you are not always going to want to be locked down. Definition can be adapted as conditions change or your work rate varies. We have used Cohaesive™ cordlock adjusters where they improve function, inverted vent zips for quick climate control - the vent position also means you can access the pockets on your inner layers without undoing the jacket.
We know you are going to be wearing a rucksack a lot of the time so we have designed the placement of the pocket and vent zips to stay clear of your shoulder straps and hip belt, or climbing harness.
Fast hood adjustment, wired peak, chest pockets, draft excluders, pit zips for ventilation, internal storm flaps, YKK AquaGuard zips all contribute to the full package.
Definition is destined to become a faithful companion on your epic adventures for years to come.

Used this jacket in Chamonix skiing this week and it was fantastic. Completely waterproof and windproof and a great fit. Way better than jackets for twice the price from the famous skiing brands.
Just used this jacket for a week of winter mountaineering in Scotland, including the wrath of storm Doris. The jacket was outstanding! Excellent breathablity and totally wind proof in what was gusting up to 70mph at times. Love it!
I have used this jacket a few times for skiing since I bought it and I love it! It totally blocks out the wind and is still very breathable. Looking forward to taking it out the Scottish highlands for a bit of mountaineering and climbing in a couple of weeks time. Great job guys!
A good waterproof is an expensive essential for any mountain walker with prices now eye watering for the best kit. But yet again Alpkit have bucked that trend with a well thought through jacket at a sensible price. At 500g it saves 250g off the jacket it replaces and yet is sturdy and windproof (and well tested in the lakes this December!). At this level good waterproofing and breath-ability is a given as are the layout of pockets. I'm 6'2" and wear an XL. If I wanted a shaped fit I'd probably go for a L but the size up works well over fleeces or jackets. I have a Kabatic to give insulation and the colour co-ordinated combination work brilliantly. The location of pit zips is interesting. Alpkit have moved them lower on the jacket so you dont have to faff under your pack shoulder straps. This means that they no longer ventilate your hot underarm, more the back. We'll see if works in the longer term but is a good example of how this company dont just follow fashion, but are willing to think through technical problems with a fresh eye. At £210, it's a bargain and well worthy of five stars.
