With a legendary fit and comfort, the 509 Stoke ZI Jacket features a stretchy exterior fabric and gets its warmth from lightweight, baffled synthetic down insulation. This waterproof/breathable fabric not only helps protect you from the elements, but stretches to move with you. A built-in forearm goggle sham keeps visibility high while the jacket’s pocket layout has been designed for use with an avy pack.
