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.
The original Alpine Ultra has been acclaimed as the perfect Alpine Jacket, but it's won friends in the Himalayas too as the ideal example of light and warm. Now this K Series version is just as warm and a full 50gm lighter with all the features and capability of the original. Enough said.
Facing an early morning start, a cold wind high up, even an unexpected bivvy. Whenever you're going to need extra warmth on your peak, it doesn't come any lighter than the Alpine Ultra. It's lighter than fleece, much warmer, packs a lot smaller and has a 100% windproof outer too.
Chest pockets and a large (optional) hood allow harness and helmet use.
Note: The optional hood needs to be ordered at the same time as the jacket.
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.
