Rab

When you need flexibility and protection in a lightweight package, these technical alpine pants are fine-tuned for the toughest vertical missions and long, hot multi-pitch routes. A highly breathable version of Rab's popular winter mountaineering pants, the Ascendor Light Pants are engineered with ultralight, durable Matrix™ fabric and a slim fit that won't hold you back on fast ascents. With only the essential features and fabric, they’re barely noticeable when worn, yet tough enough to stand up to rock, tools, and the demands of alpine use.

The pants have been designed for optimal mobility on the climb, with a long-length gusset at the crotch and climbing-specific knee articulation giving you the freedom you need when you’re making the crux move. The lower leg is tapered to allow you to easily find the next foothold, yet is stretchy at the hem so that it can fit securely over most summer alpine boots. Kicker patches reinforced with Matrix™ RX provide extra durability, while the specially placed zipped hand and thigh pockets give access to the essentials when you’re wearing a harness. The lightweight, fully exposed part-elasticated waistband with double snap closure is comfortable and low-bulk, with low-profile belt loops allow you to customize the fit.

Lightweight, slim, and impressively tough, the Ascendor Light Pants are a go-to pant for summer alpine adventures.
