The Arc'teryx Women's Procline Hybrid Hooded Jacket combines the warmth of fleece with the weather resistance of a softshell, so you can wear it during those thigh burning ascents that don't require a hardshell. The outside of the jacket is composed of Arc'teryx's Tyono 20 denier shell material, which is treated with a DWR finish to repel moisture from snow and wind. Beneath that is a Polartec Classic 100 micro velour lining to wick moisture, promote breathability, and insulate against the cold. In order to enhance mobility, the jacket is fitted with stretch panel underarms to keep arms moving freely when climbing near vertical pitches of rock and ice. And when you need a little more protection from the elements, you can comfortably layer the Procline under a hardshell thanks to trim and ergonomic design.
