Introducing Argonaut: light, packable and reliable with a fully featured hood and best in its class performance – don’t let wet weather hold you back.

The Argonaut’s relaxed fit leaves plenty of space for you to layer it over a fleece or base layer, and room to move whatever the activity. It really is the Swiss Army knife of waterproofs, equally at home strolling up fells, riding churned up bridleways or wrestling tents up in a downpour.

With 10K/10K (HH/MVTR) performance for waterproofing and breathability the Argonaut will keep you protected and dry in all but the most extreme of British weather conditions. It’s also light and flexible for moving in or stashing away in a pack thanks to the 2.5 layer construction (it uses a super-thin PU backer to protect the membrane, reducing weight).

When you're working up a sweat on steeper inclines, the mesh-lined pockets can dump extra heat by doubling-up as vents. Additional thoughtful features include the fully adjustable roll-away hood and velcro-adjustable cuffs.

Care & Environmental Advice

Product Care Information

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.

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.

Singletrack Review the Argonaut

This jacket performs excellently in a huge range of conditions, and while I only tested it on the bike in winter, I have no doubt it would suit other activities just as well at other times of year.
