A longtime Oiselle favorite, the Vim Jacket is a water-resistant, lightweight outer layer that'll protect you from the rain but keep the air flowing around you as the miles go by. It'll be your go-to lightweight shell anytime, even during dark early-morning and evening runs, thanks to reflective trim on the chest and back panels. Adjust it to fit you perfectly with bungee cords on the hem and hood. When the sun comes out, you have options: roll up the hood and stash it away, or pop the whole jacket in the self-storage front pocket with an elastic strap for easy carrying.
