Montbell offers a wide selection of ultralight and lightweight jackets. Montbell’s lightest jackets are their Wind Jackets that are incredibly compact and lightweight. When you need more insulation, their Ex Light and UL Down jackets offer high loft down and wind/water resistant fabrics to keep you warm, and not weigh you down. For potentially wet enviroments, the Thermawrap jackets have almost as good warmth to weight ratios as Montbell’s down jackets, but the Thermawrap jackets insulate when wet and absorb very little moisture. The Alpine and Alpine Light down jackets are designed for colder alpine conditions and offer more insulation to keep you warm. Montbell also offers several waterproof/breathable jackets to keep you dry, some are Gore-Tex, some are Montbell’s proprietary waterproof/breathable technology.
