Rab Ascendor Hoody – Technical Fleece for Mountaineering and Mountain Sports

Description

The Rab Ascendor Hoody is a technical layer designed for intense alpine activities where thermal regulation, breathability, and freedom of movement are essential. Conceived for technical mountaineering, winter climbing, ski touring, and fast ascents in cold conditions, it combines lightweight insulation with a highly breathable construction oriented towards continuous movement.

Its combination of Thermic™ G fabric with a grid fleece interior and Matrix™ softshell panels allows it to maintain a balance between warmth, moisture wicking, and light wind protection, making it one of Rab's most versatile active layers.

The slim fit and low-volume design make it easy to use both as an outer layer while on the move and as part of a technical mountain layering system.

Real Technical Performance

The Ascendor Hoody is specifically designed for activities where you alternate between intense effort, changes in pace, and constant exposure to cold and wind. The internal Thermic™ G fabric provides lightweight insulation and excellent moisture management thanks to its grid fleece construction, which reduces weight and improves ventilation.

Matrix™ softshell fabric panels add durability and light wind protection without compromising mobility or breathability. This makes the garment perform especially well during technical ascents, alpine couloirs, winter climbing, or fast ski touring.

The low-profile, helmet-compatible hood fits perfectly under a climbing or mountaineering helmet, while flat seams and an articulated pattern significantly improve comfort during prolonged technical movements.

Its lightweight and fitted construction also allows it to be easily combined with hardshells or warmer thermal layers when conditions worsen.
