still have yet to use it in cold temps, but fully confident it will be awesome. i lay in it all the time in my house.
Great pant...especially the fit. Nice and slim but still enough room to move. Good breathability and side zippers. Suspenders are a nice addition. Only problem is, there is no hook attached to the minigator like one would expect to attach to boot laces. There are loops on each side of the minigaiter for a strap of sort, but i have yet to find a good setup. right now i'm just using some cord to loop under my shoe. Neither backcountry.com or patagonia has been able to find a good strap for this use. will post when i find a good setup.
good pant, but I decided to return them because they are pretty baggy given the recommended sizes. I like a slimmer cut.
