Thorlak Lightweight Insulated Jacket – Jottnar

Description

Lightweight, insulated, windproof and water resistant jacket for changeable conditions.

Body-mapped synthetic Thermolite® EcoMade insulation and a mechanical stretch, rip-stop outer with a durable water repellent finish.

Barely-there stretch hood band and elasticated hood aperture with peak. Harness-compatible fleece-lined pockets, secure chest and internal pocket, Jöttnar’s anti-snag hem cords, stretch cuffs and YKK® zips.

When to use— Trekking, climbing and skiing as a midlayer under a shell or a standalone in dry cold. A lighter-weight synthetic insulated option compared to the Floyen, with a stretch outer suited to high-output activity.

Thermolite® insulation— Thermolite® is a breathable synthetic fill engineered for warmth retention even when wet — unlike down, it doesn’t collapse when damp. The insulation is body-mapped at 40g/m² — lighter weight than the Floyen’s 100g/m², making this the faster-moving, more packable synthetic option.

Stretch outer— Windproof micro ripstop stretch nylon outer with DWR finish. The mechanical stretch allows full arm movement without the jacket riding up or restricting reach.

Hood— Stretch hood band keeps the hood minimal for under-helmet use without adding bulk. Elasticated aperture with front peak for weather protection when the hood is deployed.

Pockets— Harness-compatible fleece-lined hand pockets. Secure chest pocket. Internal valuables pocket.

Weight & packability— 340g. Packs small into a pack or bag.
