When it comes to ultralight insulation, it's hard to beat Montbell, and these down pants prove it again. These are the no-frills pants you want to keep you warm when you need them and then forget about when they're stuffed in your pack. The cross-hatched baffling means the down insulation stays in place and doesn't make uncomfortable bunches. The drawcord at the waist and elastic cuffs around the ankles seal out drafts on your lower body. Perfect for around camp or to add warmth to your sleep system.
These pants keep my nice and warm when I am sitting working for long periods of time. The fit is good. If I could make one change in these pants, I would put at least one pocket in the back to accommodate a cell phone.
