Montbell offers some of the lightest pants available. The 2.4 ounce UL Wind Pants cut the wind, and the Dynamo Wind Pants do the same but have increased range of motion. The UL Down Inner Pants at just 6.8 ounces add an amazing amount of warmth for their weight. The UL Thermawrap Pants work better in potentially wet environments. The UL Tec Down Pants have reinforced areas for better durability while climbing. Montbell also offers several waterproof/breathable pants to keep you dry, some Gore-Tex, some are Montbell’s proprietary waterproof/breathable technology.
