Riding through microclimates demands layers that can breathe on the move, especially in spring and summer when conditions can shift mid-ride. At Ornot, we think in three parts: a next-to-skin layer to manage moisture, a breathable midlayer for light insulation, and a lightweight outer layer for wind or fog. The goal is simple: start slightly cool, adjust with effort, and stay comfortable as the ride warms up.

I run warm and almost always prefer lighter layers next to skin with something packable on top. After four years riding year-round in Vermont, and now dealing with the Bay’s microclimates. I’ve learned that starting slightly cool works best. Most days I keep it simple: breathable layer next to skin, light insulation if needed, and a vest or shell I can stash mid-ride. It’s a system that works from foggy summer mornings to long spring climbs.
