Fit descriptions

All garments are designed and fitted to suit their intended end use. See below for a general description of our fit categories:

Slim

A streamlined silhouette. Cut trim following the contours of the body. Expertly placed articulation of seams and the use of stretch fabric ensure maximum freedom of movement in these close-fitting items.

Regular

Neither slim nor loose. Regular fit items are the perfect balance of form fit and ease of movement.

Relaxed

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

Whether you’re on an icefall, skin track, or exposed rockface, the Ascendor Summit Hoody insulates, breathes and deflects windchill to keep you comfortable. It’s built with body-mapped fabrics to regulate your temperature, with a highly breathable and wicking PrimaLoft® Evolve lining positioned in the front and back, and wind-resistant Pertex® Quantum Air overlays on your chest, shoulders, and upper arms. Soft, gridded Thermic™ G has been placed in areas where you need minimum bulk and maximum mobility, such as the underarms, sides, and hood. The result is active insulation that adapts to any vertical mission, from winter climbing and alpinism to ski touring.
