Box-wall jacket for ultimate warmth
Crux confidently asserts that for its weight, the Pyro is the warmest jacket you will find anywhere. We can believe it. The secret to its warmth lies is its meticulous box-wall construction, which unlike stitch-through down jackets, minimises cold spots and heat dissipation. These baffles are stuffed with premium 850 fill power Polish goose down, while a longer length and an adjustable hood further help to lock in vital warmth. The two hand-warmer pockets are complemented by an internal chest pocket to complete a functional feature set that offers all you need with nothing you don’t.

- 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.
