Built for serious cold-weather performance, the Mens Stoney Creek ThermoFlex Jacket is designed to keep you warm when conditions turn harsh and movement slows down. Whether you are glassing from exposed ridgelines, spending long evenings around camp, or layering up during alpine trips, this jacket focuses on delivering warmth without unnecessary bulk.

The 220gsm PrimaLoft Silver Down Blend insulation traps heat effectively while maintaining comfort and flexibility through the jacket's 4-way stretch construction. Welded seams and wind-resistant fabric help shield against biting conditions, while the fleece-lined pockets and stretch cuffs improve warmth retention during long periods outdoors.

Despite its high insulation level, the ThermoFlex Jacket remains highly packable, compressing neatly into its own stuff sack when not needed. The Bayleaf colourway also includes a blaze-lined hood for improved visibility in the field. For winter layering, cold-weather camps, and exposed alpine conditions, this jacket is built to stay comfortable when temperatures drop hard.
