Definition [Womens] stormproof jacket
Womens technical mountaineering jacket designed to perform in the harshest conditions. Durable, breathable, full unadulterated storm protection.
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... 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've used 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.

My husband bought me this jacket last month as we are doing a lot of hill walking at weekends and going to be walking up Ben Nevis in September, this is the best jacket I have had in 20 years, got caught in torrential rain last weekend it performed very well, I felt both dry and warm, the wind did not get through and I did not experience the build up of condensation that I have with lesser jackets. love the hood and the fit is great, the scoop covers your bottom nicely to give that extra protection. I wear between a 10 & 12 top and ordered the 12, its a great fit and I can get my lightweight down jacket underneath. i'm so pleased with the quality & service from Alpkit that I have just ordered the definition for my husband.
I bought the jacket over a year ago after my berghaus paclite jacket finally gave up after 10 years. So far its done 2 winter seasons in the caingorms going mixed climbing and numerous scout weekends and dog walks. It is still 100% waterproof and the fit is really good with space underneath for big fleeces to keep warm. I'm 6'2" so bought a size large and the sleeves are nice and long as is the back length so it doesn't ride up. The material seems to be very tough and has survived ice axe points going in the wrong direction.
It would get 5 stars but I find the pockets go too far down the jacket and so when I put my hipbelt on I need to shuffle everything in them up so they don't get squished. The side vents are a little hard to operate but they don't get covered by your rucksack straps so that evens it out.
Pros: I like the jacket, it is light, functional and easy to wear, good colour and as always great service from Alpkit. Oh and it seems to be dog resistant as one tried to bite my sleeve!
Cons: I am a walker / rider and have trouble keeping the hood down in the wind as the adjusters don't stay put.
I had to go up a size (12) to get this around my hips with my down jacket on (my other Alpkit jacket is a 10) even though it states its designed to go over your kit.
Overall I am happy with the jacket and would recommend it
My wife has had one of these for 8 months or so. She loves the cut and fit BUT after light use over that timeframe the face material is wetting out badly. A gore tex pro jacket that I’ve had for 4 years is still brilliantly repellent. I will have a go at reproofing my wife’s jacket (as I do with other jackets) but our view is that the definition fabric just doesn’t stand up to even moderate use.
Thank you for your honest comments. Our jackets (and many jackets produced within the last year or so) will need reproofing more regularly as the industry moves away from harmful DWR coatings which contain PFOAs / C8 PFCs and above. C8 PFC were fantastically durable but also bioaccumulative in the environment so we now use the less-harmful C6 PFC DWR. How often you reproof depends on how often you use it, but I would expect it to be required at least a couple of times a year, more so with heavy use.
