Flux Jacket

One layer for every step of the hunt. The adaptive insulation breathes and moves more moisture when you're dragging a sled or setting a big spread and retains more warmth when you're stationary. The shell fabric has plenty of stretch and durability to accommodate high-output stints and rougher environments. It sounds too good to be true, but wear it all day without sweating or shivering and you'll never leave home without it.
