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.

This jacket is now also available in custom sizes. Specify Body Width, Body Length, and Arm Length independently to order a made-to-measure down jacket. This tailor-made service can cope with sizes from XXXS to XXXL and is ideal if your chest/waist to height and/or arm ratios differ from standard, ready-to-wear patterns.
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.
Please note: If you order a custom-sized version of this jacket it will take longer (approximately 45 days) to be manufactured ready for dispatch. Custom-sized versions of this jacket are not returnable and customer loyalty discount cannot be applied.
