The UL (ultralight) version of the Alpinist, here offered as a 28° high mountain summer sleeping bag. This is the thruhike setup for those finding limitations with backcountry quilt usage: eliminate the drafts, no straps to get tangled in, convenient head coverage without a full burrow or down balaclava.

22.4 oz in size medium for an all around wrap of lofty down with the unique center zip that allow sitting chores with your back and head covered.

Only the lightest fabrics and materials are applied to the Alpinist UL. 

The down fill is carefully calculated and graduated to provide maximum insulation where it matters. 

Extensive custom options allow case by case sizing and/or further weight savings.

Optional weather proof shell in full or partial coverage.
