Rab Ascendor Summit Hoodie

What Our Gearhead® Experts Are Saying:"I wear the Ascendor Summit Hoodie when I need warmth without overheating on steep winter climbs. The hybrid design dumps heat on the move, and the wind-resistant panels cut the chill up high. It’s one of the most technical fleeces I’ve used—it layers great and moves well on route."Alpine climbing demands balance: warmth without bulk, breathability without exposure, and gear that works with us—not against us. That’s where the Ascendor Summit Hoodie from Rab comes in. Designed for high-output missions in the mountains, this advanced fleece blends targeted insulation and ventilation with mapped weather protection to support winter movement in its most technical form.With PrimaLoft® Evolve Active insulation lining the torso and Pertex® Quantum Air overlays across the upper body, this hoody blocks wind where we need it most while allowing airflow to regulate heat on the move. Soft Thermic™ G fleece throughout keeps us warm in cold conditions, while the gridded backer enhances moisture management. Add in an under-helmet hood, thumb loops, and a streamlined fit, and this hoody is dialed for mixed climbing, mountaineering, or ski mountaineering when the weather won’t hold still.
