evo.com | Outdoor Research Activewear Jackets > Wind protection up front, laser-perforated ventilation in the back. The Outdoor Research Deviator Wind Jacket is built for the kind of efforts where you're generating enough heat to make a standard shell feel like a sauna. At just 4.5 oz, the hybrid-mapped construction keeps the lightweight stretch woven fabric where you need wind and water resistance most, while the perforated panels at the back and underarms let the heat out before it becomes a problem. Packs into its own left-hand pocket, so it's easy to stash when the trail warms up.
