Solid long underwear!
This is a pretty great suit/pair of longjohns! Easy to get on and off and nice and toasty. The hood seems like it would be annoying but is actually really great. You can wear it up like a skull cap and it helps block sun/snow or when not wearing it it isn't so thick that you notice it on your back. The only problems I have with this are that the calf/ankle section is a little tight and it's a not the easiest thing to go to the bathroom in. Besides that it's just GREAT!
