R1 Air with a hood and a full zip, which makes it the layer you can actually manage mid-effort. The hollow-core zigzag knit wicks and dries fast, the hood is cut slim enough to sit under a helmet or a shell hood, and three zippered pockets take a phone and a bar without flapping. Slim fit, built to move under a pack.
