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.

Expedition

Ideal for long bothy nights and casual days at the crag, this practical yet stylish down jacket is a go-to in chilly weather. It’s built with Pertex® 3D Weave Technology, which means the baffles can be woven from a single stretch fabric without any stitching. This improves down lofting, increases wind resistance, reduces weight, and allows the material to flex as you move. Combined with 650FP down and a windproof outer fabric, it’s perfect for bundling up on the trail, at the climbing wall, or by the campfire.

The Pertex® Quantum fabric is breathable and windproof, ideal for cold weather.
Filled with 650FP down to keep you cosy when the temperature drops.
The down-filled hood features a stretch binding to seal in the heat.
Two spacious zipped hand pockets, perfect for stashing gloves and snacks.
Ultra-snug feel thanks to the slim fit, with a drawcord adjustable hem to keep out draughts.
YKK® VISLON® front zip with fleece-lined chin guard for comfort.
Unique pre-woven baffle reduces stitching and increases weather resistance.
