Mens Strata Flex Jacket

The great thing about Polartec Alpha insulation is that it represents the best of both worlds: it's light and compressible like traditional synthetic fillings, but way the fibres are laid out makes Alpha-insulated garments breathable enough to use as mid layers. The Strata Flex takes this versatility even further with the addition of Power Stretch Fleece panels under the arms, which insulates while allowing fantastic freedom of movement.Exceptionally breathable with added freedom of movement? Sounds like the perfect spec for a cold weather climbing jacket.
