Stoney Creek Womens ThermoFlex PrimaLoft Jacket | Blue

The Stoney Creek Womens ThermoFlex Jacket is made for cold conditions where maintaining core warmth matters more than carrying a light summer layer. Previously known as the Thermolite, it combines high insulation with a flexible build that avoids much of the bulk associated with traditional insulated jackets.

PrimaLoft Silver Down Blend provides the warmth, while its water-resistant treatment helps protect the fill from moisture that could otherwise reduce loft and thermal performance. Welded baffles keep the insulation distributed across the jacket, and the windproof outer fabric helps stop exposed conditions from cutting through your layers.

The 4-way stretch construction gives you more freedom to move when walking, setting up camp, or adding the jacket over other clothing. Once activity slows, the lined adjustable hood, stretch wrist panels, and fleece-lined hand pockets help retain warmth where it is easily lost.

A large chest pocket provides secure storage for smaller gear, while the included storage bag lets the jacket pack down when it is not being worn. At 945g (2.08lb), it is a substantial insulation layer intended for serious cold rather than minimal-weight travel.

It is the kind of jacket you appreciate most once the temperature drops and standing still starts to feel colder than expected.
