SOS Cosmos M Insulated Pants Black

The SOS Cosmos M Insulated Pants deliver reliable warmth without bulk, built for skiers who want straightforward protection through a full day on the mountain. PrimaLoft® Black Eco insulation at 60g/m² keeps you warm without heavy layering, and the 15k waterproof and breathability rating handles mixed conditions well.

Why we rate it

These are honest, functional ski pants that do their job without fuss. The 100% polyester shell with YKK zips and reinforced leg hems will take a season's worth of use. Snow gaiters keep powder out, and the regular fit works for most builds without restricting movement. SOS has been making kit for freeriders since 1982, so the cut and pocket placement reflect real mountain experience.

Who it's for

Skiers of any ability who need solid all-mountain warmth. The regular fit suits most leg shapes; the insulation level works best in cool and variable conditions rather than extreme cold. All-day users on piste and off-piste terrain.
