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.

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.

Expedition

Designed specifically to accommodate the layering system and equipment required for high altitude and polar expeditions.

Product codeQIO-97

The PrimaLoft® Gold Insulation uses fine, water-repellent fibres with a high warmth-to-weight ratio and excellent breathability and improved comfort during activity spikes. The tightly woven Pertex® Quantum outer is light and supple, fending off the elements while reinforced Pertex® Shield panels at the seat, knee and inner leg add extra durability at high-friction zones.

Highly efficient when damp and easy to compress, the use of full-length side zips with insulated baffles means you can pull them on over boots and regulate your temperature as conditions demand.

Synthetic insulation explained.

Synthetic insulation is strong, lightweight, and resilient. It’s ideal for environments that are cold and wet, as it’s fast-drying and remains effective in damp conditions.
