The Strafe Highlands Shirt Jacket looks like a casual button-up but performs like a technical mid-layer, combining lightweight PrimaLoft Active Evolve insulation with highly air-permeable stretch face fabric treated with DWR to repel light weather. Quick-drying and breathable enough to work through a wide range of mountain conditions or everyday wear, this mock neck shirt jacket features open welt hand pockets with interior drop pockets and a snap closure chest pocket for stashing essentials.
