The Under Armor 4.0 base layer is great under my ski pants. No need for a second layer on it even on the coldest days as I did with the 2.0 base layer.

I got these to keep me warm for the Bills playoff games. I used to use the regular Under Armour leggings. But I wanted something warmer and these were on sale. I'm so glad I got them. They were the best I've ever had. My legs stayed warm all game after being outside in the single digits for over 9 hrs. I definitely recommend them and the Base 4 shirt too.

Sizing up the man: Waist: 33", Hips: 37", Inseam: 33" Thighs: 21", Calves: 14", Ankles: 8.5" Weight: 160 lbs Pros: The inseam can't be 30.5" it's to perfect. It's has to almost be 32", The butt is a little baggy, but I'm not a super active guy, so my butt is on the small side. The waistband is comfortable. You can lounge around in these and be comfortable physical and thermally. They are so much warmer than the Base 3.0s. They are truly "fitted" for my shape. Slight hug on the calves nothing uncomfortable or compression like. There is no discomfort on my thighs either. They seem to wick moisture very well. I will be buying another pair of these. Oh, the quality is there. When you get them on, pull them up to much then slide everything down to where it's comfortable. Straightens out the leg hairs if you have them. More comfortable that way too. Right, the fabric is strong and a great thickness. I wasn't sure how "leggings" would feel but dude. I love them. Where have these been my entire life. I will be wearing these as much as possible during the winter.
