Slim

Regular

Relaxed

Our more generous fit. Cut loosely through the body allowing for ease of movement and additional layering.

Next to skin

Remains in contact with your skin and is built with stretch fabrics for complete flexibility, making it easy to layer and ideal as a baselayer.

Tech and features.

Adapted to a range of activities from fast hiking to long-distance trekking, these breathable shorts are ideal for cooling off on warm days in the mountains. Constructed from lightweight, fast-drying Matrix™ stretch fabric, they’re fine-tuned for fast-paced exploring and keep you comfortable as you pound out the miles.

Minimalist and ultralight, the shorts have a pull-on style which reduces weight and bulk. The supportive elasticated waistband is perforated to allow airflow when you’re working up a sweat, with a simple internal waist drawcord that you can use to adjust the fit. Stash supplies in the two open hand pockets, with mesh pocket bags for additional venting.

Designed to feel virtually weightless when you’re on the move, the Momentum Light Shorts are ideal for keeping up the pace when the mercury rises.
