The seasons change, leaves deepening into golden yellows and deep crimson, and despite the chill in the air you would argue it's the best time to ride. It also helps that you're wearing the highly breathable Trail-Series Alpha Jacket. This thermal midlayer is great for shoulder season adventures--it's built with a wind-resistant face, and lofted fibers against the skin that trap warmth while still allowing heat and sweat to escape. It's soft enough to wear directly against your body, but fitted to allow room for a base or two.
