There are two simple rules to ensure longevity:
- Always store your jacket uncompressed in a dry, airy place
- Try to keep it as clean as possible to minimize washing (this ultimately damages the down)
We highly recommend you hand-wash your down garment or, alternatively, use a professional service.

Crux kit is designed for mountaineers, by mountaineers. Well, actually, by one mountaineer – since this specialist brand is entirely owned and operated by New Zealander Carol McDermott.
Carol is a trained chemicals and materials engineer with a background in the outdoor industry. He’s also a highly experienced alpinist and climber, with ascents in most of the world’s great ranges to his name. That’s a pretty good CV for designing the world’s most uncompromising outdoor kit, focused purely on performance in the most demanding conditions. Which is why Crux use only the best quality materials, like Polish white goose down and premium Japanese fabrics, with stringent quality control that puts the big brands to shame.
