evo.com | Outdoor Research Insulated Jackets > The Vesper Insulated Shirt Jacket splits the difference between a flannel and a puffy, wrapping VerticalX Eco SR insulation made from recycled polyester and Sorona inside a bluesign-approved 20-denier ripstop stretch shell. Zippered hand and chest pockets keep essentials secure on the trail, and the left pocket doubles as a stuff sack for packing it down when the day warms up. Adjustable cuffs cinch tight against the wind or loosen over bigger gloves, making this the piece for cool-weather travel days and shoulder-season camp mornings.
