The Sleepwalker is a versatile reinforcement insulation garment for cold expeditions. A reversible multi-tool with full zip on side which makes it easy to put on, and take off. Padded with 80g Ecosphere, it will keep you warm and toasty no matter what.

Stylish enough to wear when you are relaying at the climbing cliff or out and about in the city. The Sleepwalker can also be used as a short elephant foot for the sleeping bag. When it’s finally worn out bring it back to Houdini for recycling.
