You may study the weather maps and plan your expedition accordingly, but if you still manage to get caught in cold, wet weather, youAAAll be glad you brought along the Sherpa Adventure Gear MenAAAs Raajen Primaloft Hooded Jacket. Super-light PrimaLoft One insulation works to you warm in chilly conditions and doesnAAAt throw in the towel when it happens to get a little wet. A DWR finish on the lightweight ripstop shell also helps keep moisture at bay, and the Lycra binding at the hem prevents the wind from whistling up your back. The insulated, helmet-compatible hood traps heat that tries to escape from your head, and three zip pockets hold any essentials you might need to get to quickly.
