Lightweight insulation is like wearable magic on ski tours and alpine climbs, and the Stoic Luft Hoody wants to be the magic in your pack. Stoic gave the Luft 100-grams of lightweight, synthetic Cirrus insulation and a warmth-retaining hood to help you brave alpine walls and early-morning skin tracks. The Luft's 3-D ergonomic fit offers a layer-able fit that won't restrict or inhibit motion whether you're on belay or heading for seconds in your favorite backcountry stash.
