In our wet and windswept corner of the planet, we sometimes forget just how big a deal a decent breathable waterproof jacket is. It’s not just staying warm and dry, it’s the possibilities it opens... 

Simple doesn’t have to mean basic. Introducing the 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.

Environmental Considerations

The chemical finish that keeps water beading off your waterproof jacket has changed.
As with all waterproofs from responsible outdoor brands, our waterproof jackets meet international environmental standards and require occasional washing with a technical wash to maintain their high breathability.
This wasn’t always the case. Years ago, waterproof jackets were treated with chemicals that had toxic by-products that lingered in the environment for generations. Those old chemicals needed little maintenance, whereas modern waterproofs need regular washing.
We fully support this change. In fact, we quite like the idea of taking time to look after our kit so that it lasts a long time.
We are committed to reducing the environmental impact of all our products –in fact it’s in our DNA: we can’t imagine ever doing anything else. We always review the materials we use, manufacturing methods and our own consumption of resources. We do the research, make informed decisions, and choose the best option available to us.

Product Care Information

To maintain the high performance of your waterproof, we recommend you wash and re-proof once or twice a year using specialist products like Nikwax or Grangers. For more information, read our detailed care instructions.

Brilliant value for money jacket

We’ve three Argonauts in our household; one for me, my wife and my daughter! It’s a very nicely cut jacket, for both sexes, and looks just as good on the highstreet as it works in the hills. If I could make one improvement it would be the ability to stash the hood a little more neatly as the current roll-it-and-loop-it system is a bit untidy. A brilliant value for money rainshell overall though. Buy one today!

Bought my Argonaut in the new(ish) Keswick store four weeks ago. Yet another piece of super quality kit from the best outdoor suppliers ever! Lightweight, comfortable and breathable - and a great fit over my Alpkit Heiko mid layer.

Great Jacket, Top Performer

Really pleased with this Waterproof Jacket from Alpkit, Wore it a few times when its been raining hard and kept my base layer totally dry. Love the peaked adjustable integral hood. Good size pockets. Once again the staff at Alpkit were really helpful. This is a top class company that makes you feel a valued as a customer.

Solid jacket

Amazing compact jacket. Use this in Iceland this past weekend survived driving rain and wind, no wet patches at all. Surprised by the compact size it can squeeze down to. Great jacket thoroughly recommend it.

Light weight and sturdy

Feels like it’s well built kept me dry so far! And is nice and light for easy storage. Would of been nice to have poppers and a slightly higher quality zip as the Velcro and zips feel a little more on quality compared to the rest of the jacket.

Alpkit Argonaut

Nice jacket, comes up a bit small, so ok for summer, and a bit short too. The fabric is waterproof, and the seams are very well sealed and waterproof. But the pockets leak badly even when closed. My belly was soaked after 20 minutes fairly heavy rain, even with no wind.

Poor performance

The jacket keeps out rain but has poor breathability. I returned my jacket and it was replaced. However, the replacement doesn’t perform any better. The jacket feels clammy very quickly and becomes wet (from sweat).

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.
