POWERFULLY LIGHT. WEIGHTFULLY WARM.

A brand new lightweight insulated jacket, built for mountain missions where every gramme counts. Thorlak is a remarkably warm, windproof and water-resistant jacket, with a lightweight and packable focus.

For reliable warmth even when wet, we body-mapped synthetic Thermolite® insulation and wrapped it in a mechanical stretch, windproof, rip-stop outer, complete with a DWR finish. A powerful and dynamic mix beneath a clean, minimalist aesthetic.

Features include a new barely-there stretch hood band for under-helmet comfort, elasticated hood aperture with front peak, harness-compatible fleece-lined pockets, a secure chest and internal pocket, plus Jöttnar’s anti-snag hem cords, technical stretch cuffs and YKK® zips.
