Efficient warmth and breathability for fast, technical movement
Rab says:
When you’re working hard swinging ice tools, ascending steep slopes, or moving fast, the Ascendor is designed to regulate your temperature and keep you comfortable. Constructed with a grid fleece fabric that balances warmth, wicking, breathability, and mobility, it adapts to the conditions and your output, so you can make smooth progress. Stretchy and slim fitting, it’s easy to layer and ideal for climbing and technical ascents in cold weather.
Our Verdict
Rab’s Ascendor Pull-On is a light, close-fitting fleece designed for steady output in cool to cold conditions.
Weighing 340 g (Medium), it features a gridded Thermic G fleece with a smooth, durable outer face and a soft inner that balances warmth with quick moisture transfer. The deep front zip provides easy ventilation on steep climbs, while the fabric's stretch ensures complete freedom of movement for scrambling or mixed routes. The slim fit layers neatly under a shell without bulk, and the extended hem and snug cuffs help retain warmth during active use.
Breathability is excellent during uphill work, and the material remains comfortable across a wide temperature range. Well constructed and reliably warm when moving, the Ascendor Pull-On delivers dependable performance as a versatile, low-bulk midlayer for technical mountain days.
