Warmth & Weather Protection

The Cosmos is designed as a warm, insulated ski trouser for women who want protection from cold and wet conditions without sacrificing mobility. PrimaLoft® insulation provides additional warmth, making the trousers well suited to colder days when built-in insulation is preferable to relying solely on additional layers.

A 15K waterproof TPU membrane, combined with DWR treatment and fully taped and welded seams, helps prevent snow and moisture from penetrating the trouser construction. The windproof outer further improves protection when skiing in exposed or blustery conditions.

Breathability & Ventilation

With a 15K breathability rating, the Cosmos is designed to release moisture vapour generated during active skiing. Ventilation zips provide additional airflow when temperatures rise or during higher-output activity, helping you regulate comfort throughout the day.

The stretch feel and regular fit also allow the trousers to move naturally with the body, making them suitable for carving, skiing variable terrain and general resort use.

Fit & Ski-Specific Functionality

The Cosmos features a regular fit with a medium rise, complemented by an adjustable waist, elasticated waistband and belt loops. This allows the fit to be personalised while maintaining a secure feel during skiing.

At the lower leg, integrated snow gaiters help prevent snow entering around the tops of ski boots, while reinforced boot cuffs provide additional durability in an area exposed to ski edges and equipment. Zipped pockets provide secure storage, including a dedicated leg pocket, and YKK zippers offer dependable operation in winter conditions.
