Waterproof mountaineering jacket for the harshest of conditions: impenetrable storm protection, whatever the mountains throw at you
Details

Packed full of features, Definition is the ideal mountaineering jacket for year-round Munro bagging, Scottish winter epics and committed alpine climbing.

  • A world's first PFC-Free mountaineering-ready waterproof
  • High performance waterproof and breathable 3-layer protection (30K HH/20K MVTR)
  • Extremely abrasion-resistant nylon 6,6 outer fabric

A fortress of a jacket, the Definition has been designed to safely encase you from the wettest, windiest, and wildest of mountain weather. We’ve used a 3-layer construction that's highly waterproof (30K HH) and breathable (20K MVTR) - comparable to the performance of branded fabrics like Goretex Pro - to provide long-lasting performance and protection from exposure.

The outer fabric is made from extra durable nylon 6,6, to ensure it'll stand up to serious use and abuse. Whether you're scrabbling up chimneys or scraping along traverses this material provides outstanding tear and abrasion resistance and the fabric's plain weave creates a smooth surface that resists catching.

Designed to sit over multiple layers, the Definition is cut with pre-shaped arms to avoid riding up and exposing your back or tummy when you’re reaching up for holds or swinging ice-axes.

A large hood is sized to comfortably fit over a climbing helmet, with a wired peak and three elastic adjusters allow you to really batten down the hatches when the weather rolls in.

A two-way water resistant YKK Vislon Aquaguard main zip (complete with internal storm-flap) accommodates harnesses, completing the mountaineering-ready feature set.

Sustainability and Product Care
The better you look after this jacket, the better (and longer) it’ll look after you. Well, when we say ‘look after you’... it’s not gonna make you cups of tea or bring you breakfast in bed, but it will keep you nice n’ dry. And the good news is: it’s dead easy to do. 1) After you’ve finished going nice places and doing good things, treat your jacket to a wash at 30°C with either a dedicated Tech Wash (like Grangers and Nikwax) or pure soap. This keeps your jacket breathable by stopping the Durable Water Repellent (DWR) coating from getting clogged up with dirt and skin oils. No one likes a sweaty, clammy jacket. 2) If it’s stopped beading (rain soaking in rather than forming droplets), you can reactivate the factory-applied DWR by sticking it in the tumble drier on a low setting or applying a cool iron to it (under a tea towel). 3) To keep your jacket beading, you’ll probably need to top up the DWR once or twice a year using a Grangers or Nikwax re-proofer. You can find out more about why this is important here. If you’re still a bit unsure about washing your jacket, you can also take it/send it to our Ambleside store’s waterproof washing service and we’ll sort it all out for you.

We treat all our waterproofs with PFOA-free DWRs, cutting out some pretty nasty chemicals. Unlike our insulation and sleeping bag ranges, our waterproofs are not yet PFC-free. We’re still looking for a PFC-free DWR that’ll provide the same long-lasting performance for waterproofs, but we are working on it!

We make gear you’ll love for longer: gear that lasts; gear you’ll use, repair, re-use and pass onto someone else when you’ve finished with it. That’s why all our products have a three-year Alpine Bond warranty as minimum. We’ve always thought that the most environmentally friendly product we can make is the one that gets used the most and lasts the longest. So that’s what we do - it’s pretty simple really.
