Filament Hoody - Men's (Spring 2022)



Lightweight, fast-wicking fleece for high-output alpine adventures

Where high-output sport meets cold mountain weather, you’ll find Rab's Filament Hoody. With lightweight, fast-wicking Thermic™ fleece, it is the ideal midlayer for steep alpine ascents, backcountry ski tours and big mountain adventure.

The Filament Hoody is made from Thermic™ fabric, an engineered fleece designed to be light, warm, durable and quick-drying. Comprising recycled polyester with 7% elastane for easy stretch, it features a full-length YKK® front zip for easy venting on the move, plus a secure YKK® zipped chest pocket and a warm under-helmet hood. While discreet thumb loops help keep your hands warm and your sleeves in place, the use of low-profile seams helps ease the friction between layers, improving comfort against the skin and eradicating chafe points during intense mountain activities.

As part of Rab's Ascent range, the Filament Hoody comes with a layer-friendly low-bulk fit and a weight of just 274g. Warm, flexible and dry, it is as practical for ski mountaineering as it is for technical winter climbs.
