A lightly insulated technical layer that combines an abrasion-resistant Pertex® Quantum outer shell with responsibly sourced 800-fill HyperDRY™ water-repellent down.

From ridgeline transitions to breezy belays and cool nights in the desert, our Women’s Pinion Down Sweater is the perfect way to equalize unexpected chills. A lightly insulated layer that’s packable enough for the mountains and stylish enough for drinks back in town, the Pinion features a lightweight and abrasion-resistant Pertex Quantum® ripstop shell that blocks wind and light precip. Also featuring responsibly sourced, 800-fill HyperDRY™ water-repellent down, this light jacket will stay warm and lofty through mixed conditions. The Pinion offers low-bulk comfort under a harness or paired with leggings, and the included stuff sack lets you quickly stash it away in a pack or shoulder bag.

Pertex® Quantum Shadow Ripstop, 100% Nylon, 20 denier, 37 g/m2 with 80/20 DWR Finish

Pertex® Quantum is built for maximum strength, while staying lightweight and soft without sacrificing resistance. Made with 20D nylon and a DWR finish, it's lightweight while still offering excellent wind resistance and water repellency. The shadow ripstop creates the look of traditional ripstop without the raised weave, resulting in a modern twist on a traditional outdoor fabric.
