Mountain Core Jacket

Combining revolutionary PrimaLoft® Active insulation with our own lightweight and wind-resistant Flexile shell, the Mountain Core Jacket is an incredibly effective insulating layer that still provides excellent breathability during activities with variable output. The cozy lined hood provides welcome protection from cold winds.

PrimaLoft® Active is built from a synthetic plume woven through a knitted mesh, offering the warmth of a fleece but with less than half the weight. With all the benefits of synthetic insulation, Core products work wet or dry with incredible wicking properties to ensure you won’t stay wet for long. Using the 125g/m2 weight of PrimaLoft® Active means 65% of the insulation is derived from recycled sources.

The stretch nylon Flexile shell fabric has a high degree of wind and water resistance whilst retaining good breathability, perfect for mixed conditions.

Pair with a shell in bad weather to increase the insulating benefits and protection.
