This K Series product has been created for one single reason, to take warmth-for-weight performance to the limit of what's possible. Unique 1000 down, super-light materials, and specific design features mean that the word Ultralight now applies to this wide range of gear that will take you to the Poles as well as on a Sahara Marathon.

Also available in custom sizes. We make clothing to order, so if you’re not a standard size we can make it to fit. To order a non-standard custom size, select the Custom Sizing tab, choose your body width, and then the body/arm lengths, shorter or longer, that work for you. A custom size takes us a little longer (typically two weeks longer) to make and, because it’s personalized, it’s non-returnable and our customer loyalty scheme can’t be applied.
1000 down and 10X inner, the exceptional lightweight components of the K Series, have allowed us to make a down jacket at 240gm (8oz) which weighs less than most down vests. But make no mistake, this Ultra Jacket is a piece of real outdoor kit: the 1000 down gives surprising warmth inside the highly water-resistant and windproof Ultrashell outer.
It shares the pared-down design principles of the whole Ultra range: elastic at side-waist, light Lycra cuffs, waist-level front pockets, zipped inner security pocket, and a drop-tail back.
