When you're carrying your life on your back, keeping things light is paramount; Fjallraven's Keb Loft Men's Hooded Jacket tips the scales at just over one pound, so it won't weigh you down when you're hitting the trails for a week of trekking. It also boasts G-Loft Supreme synthetic insulation, which packs down small so you have room in your pack for other essentials, and a low-profile hood flips up to keep your ears warm without getting in the way when it's hanging. Fjallraven also gave the Keb hand, chest, and internal pockets for low-profile storage when you're moving and finished the cuffs and hem with elastic binding to help keep heat in.
