I mostly wear my MontBell UL Thermawrap Pants in camp during the winter when I’m melting water or cooking, but I put them on today when we got to treeline on Mt Chocorua (3,500 ft). With a gusty wind and temperatures in the single digits, I wanted a little extra thermal protection.
This is the second season that I’ve been wearing these insulated pants and they’re one of my favorite pieces of winter kit. Like all MontBell products, they are extremely compressible which I value because I have to get a lot of other gear into my winter pack. They’re also very lightweight, weighing only 12.7 oz, for a size large including a stuff sack.
I normally put them on over my base and wind shell layers, and over my gaiters. They have a 7/8 zipper, two actually, which makes them easy to get on over plastic boots and also lets you vent easily if you get too warm. My pair is insulated with Exceloft, which is MontBell’s proprietary synthetic insulation and they claim rivals down in its thermal weight-to-warmth ration. If you do prefer down, MontBell sells a nearly identical garment called the UL Down Inner Pant.
There are a few other features about these pants worth mentioning including two hand warmer pockets, snap closures at the bottom of the legs and a drawstring waist. The shell and lining fabric is a soft 15 denier ballistic nylon that feels good and is pretty quiet when walking.
I now own a few MontBell garments and I love them all. They are really the perfect balance between features and function in an ultralight package.
