Let fall fall.
Be not dissuaded by autumn's onset. The Fox Equilibrium Long-Sleeve Men's Jersey loves the lower temperatures, and once wearing it, so will you.
Though neither windproof nor heavily insulated, the soft fleece material that comprises the jersey is warm and durable. Still, the smart placement of vents makes it breathable, so you don't sweat your face off on the climbs. The jersey tails off slightly down the back for complete coverage down low, and the neck collar does the same job up high. In back, there's a zippered stash pocket with a headphone port, and the hem and wrist cuffs are banded with elastic to keep everything in place.
The Fox Equilibrium Men's Long-Sleeve Jersey comes in five sizes, from Small to XX-Large, and in two colors: Heather Black and Heather Fatigue.
