Sustainability and Product Care
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), providing 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.
The OS map-sized main pockets and chest pocket have been designed to sit clear of your rucksack hip-belt or climbing harness, as have the innovative vents.
The inverted vent zips are easier to open and close when overheating than traditional pit-zips.
We’ve also used Cohaesive™ integrated cordlocks as hem and hood adjusters. Flat and low profile, these are easier to pinch open when wearing thick gloves. Gusseted cuffs fit easily under or over gloves, with anti-snag Velcro adjusters.
Designer’s Notes
The updated Definition is one of the very first performance mountaineering shells to use a PFC-free water repellent treatment (DWR). The unique 3-layer fabric has been specially developed by Alpkit for even more durability and uses the highest performing, environmentally-friendly DWR available.
'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... 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
'This jacket has waterproofness and breathability that compare with some of the best fabrics available... the hood arrangement is excellent, with a wired and stiffened peak, a rear volume adjustor and two adjustors at the front. Overall we couldn't really fault the Definition jacket. For the price the Definition is hard to beat.' - Trek & Mountain (Editor's Choice, Winter Shells Group Test)

Product Care Information
Caring For Your DWR
To keep your jacket’s durable water repellent (DWR) treatment in tip-top condition, wash it regularly in pure soap or a specialist cleaner. You may also need to refresh the treatment about once or twice a year (depending on usage) using a reproofer. Using a spray-on reproofer maintains your jacket's wicking ability.
Washing Instructions
Wash on a delicate cycle at 30˚C or hand wash with lukewarm water. Use a technical wash product (like Nikwax Tech Wash or Grangers Performance Wash) or pure soap. DO NOT use detergent, fabric conditioners or softeners. Rinse thoroughly in clean water. Line dry or tumble dry on low heat. You can also use a cool iron to reactivate the DWR.

We have dedicated Repair Stations in our stores and we're fully equipped to breathe new life into your old kit. This includes spare parts, patches, new zips and wash and reproofing of your down and waterproofs. Pop into any store or contact us online for more info.

Sustainability
How It Is Made
PFC-Free DWR
The Definition uses a completely PFC-free DWR treatment on its outer fabric – one of the first performance mountaineering shells in the world to do so. PFCs are potentially harmful and have been found to build up in the environment. We don't like the sound of that so we've been working hard to get rid of them.
Gear You’ll Love For Longer
The updated Definition uses a specially developed fabric that’s had durability baked into every thread. The plain weave nylon 6,6 outer fabric is even more abrasion resistant against rough surfaces. And the new 10d nylon tricot backer fabric has a smooth face which offers less resistance and lasts even longer.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.
We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
