On and off your machine, the snow-to-street 509 Stroma Fleece Shirt is the secret weapon to warmth. The smooth and easy to clean outer face fabric resists a spilled beer and slides easily under your 509 jacket. Microfleece on the fabric’s interior traps warmth while wicking away sweat to keep you dry. The 1/4 zip entry makes it easy to put on while wearing a beanie, and details like low-profile pockets add to its everyday versatility.
