The challenge: create the lightest and warmest insulation layer possible, without compromising on fit or features. The result is the highly refined MontBell Ultra-Light Down Inner Pants. This family of products delicately balances the characteristics that define reliable ultra-light apparel.The U.L. Down Jacket weighs less than most cotton thermals and blocks an amazing amount of wind, and is warmer than most heavy soft shell pants, while compressing to the size of a 32 ounces water bottle. Specifically designed as a replacement for the heavy and bulky fleece garments used by many backcountry enthusiasts, the U.L.Down Pants are モwhat you needヤ when warmth is critical, minimal weight is paramount, and space in your pack is at a premium.

        Comments about U.L. Down Inner Pants - Men's:

        These are amazingly light and warm pants. They pack smaller than a nalgene bottle and weigh almost nothing in my pack. The inseam seems a little long, but it's pretty easy to compensate by tying the pants up using the drawstring. The outer fabric isn't very durable, but just wear a shell over it and you'll be fine. They're meant as an inner layer anyway. Unless you're in really wet weather, go for these instead of fleece. They're lighter and warmer than any fleece layer. Oh, and the matching top is fantastic too. [...]

            Comments about Mont-Bell U.L. Down Inner Pants:

            The best thing about these pants is that they pack down into a very small and lightweight sack-which makes them perfect to carry for emergency purposes in very cold conditions here in Alaska. They aren't exactly flattering when on but if it's 20 below and you have a mechanical with your bike I don't think you are going to care about that. Otherwise probably not very durable for day to day wear and the legs could use a zipper or snaps around the ankle to be able to put on without removing shoes,
