A new TSM fave- the FUTUREFLEECE pant from The North Face offers some of the best warmth-to-weight ratios. It has a super soft next-to-skin feel, hand pockets, and a smaller zip pocket with low-profile cuffs for wearing under boots. If you need a midlayer pant or if you've recently switched to shell pants and need a little extra layer on those cold days, we can't recommend the FUTUREFLEECE pant enough.
