Comfortable waterproof trousers, with a neat cut to eliminate excess fabric but still allowing superb freedom of movement. Forget what you hate about waterproof trousers, these are lightweight, packable and comfortable to wear whatever the activity.

The 2.5 layer fabric is soft and quiet too, but still fully waterproof with 20K HH/ 20K MVTR performance. Check out how our 20K/20K fabrics stack up against other brands and you will see just how good these pants are. You get adjustments in the form of an elasticated waist with drawcord, plus half length water resistant zips and VELCRO® Brand tabs at the cuff, so you can pull them on over your footwear. Weighing about the same as your average sandwich, they also pack away into their own mesh stuff sack for stashing in your pack.

Care & Environmental Advice

Product Care Information

The better you look after these trousers, the better (and longer) they'll look after you. Well, when we say ‘look after you’... they're not gonna make you cups of tea or bring you breakfast in bed, but they 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 trousers to a wash at 30°C with either a dedicated Tech Wash (like Grangers and Nikwax) or pure soap. This keeps your trousers breathable by stopping the Durable Water Repellent (DWR) coating from getting clogged up with dirt and skin oils. No one likes sweaty, clammy waterproof trousers. 2) If they've stopped beading (rain soaking in rather than forming droplets), you can reactivate the factory-applied DWR by sticking them in the tumble drier on a low setting or applying a cool iron to them (under a tea towel). 3) To keep your trousers 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 trousers, you can also take it/send it to our Ambleside store’s waterproof washing service and we’ll sort it all out for you.

Environmental considerations

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.
