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.
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.
