The Squamish Jacket proves that the lightest layers make the biggest difference. Whether thrown over a tee or layered with a fleece, this durable windshell punches above its weight—blocking wind, cutting chill, and moving effortlessly with you on the wall. When the wind picks up, it’s there. When the sun breaks through, it disappears, packing into its own chest pocket and clipping to your harness, always within reach for breezy belays and shiver-inducing cruxes.
