Cold weather is where the Stoney Creek ThermoFlex Jacket comes into its own. Designed to maximise core warmth without the heavy bulk often associated with insulated jackets, it is well suited to alpine environments, exposed ridgelines, and long periods spent stationary in low temperatures.

The jacket is filled with 220gsm PrimaLoft Silver Down Blend insulation that has been hydrophobically treated to help maintain loft when conditions become damp. Combined with a windproof outer and water-resistant construction, it delivers dependable protection when temperatures start to drop.

Comfort is equally important. The four-way stretch fabric allows unrestricted movement, while the friction-free lining makes layering simple when conditions change throughout the day. Fleece-lined handwarmer pockets, a large chest pocket, and an internal drop pocket add useful storage and everyday practicality.

Despite its warmth, the ThermoFlex Jacket remains highly packable and stores neatly into its own stuff bag. It is the kind of layer you appreciate once you stop moving and the cold starts to bite. Easy to carry in your pack and ready when conditions demand serious insulation.
