Nice fit, lower on the waist than others - which is a plus for me since I'm on the petite side. I would agree with "ceo195..." in that they sit about an inch below the navel. I ordered up a size from what I might usually, following one of the other reviewer's suggestions. Thus, they do not fit like a pair of pantyhose (thank goodness!), but rather comfy enough to sleep in. Nice light warmth without the bulk. My only complaint so far is the length - they are long - but since the fit is so nice, they easily roll back without being too bulky around the ankles.

I got my first pair of these Cap3 bottoms last year, and I love them. They're comfy for sleeping in, and I wore them cross-country skiing (under a light shell-pant). They're almost too warm for cross-country skiing, unless it's a really cold day.

When these went on sale this summer, I ordered a 2nd pair... but sent them back. The legs fit about the same as my first pair, but the waist was huge. Maybe a manufacturing problem? Dunno. Still love my first pair.

I bought these pants as my only long layer for hiking 90 miles of the JMT. They were not as fitted as I expected, being a little baggy in the upper half. they were plenty warm for the evenings, which were in the 40's. I didn't sleep in them, as my bag was warm enough. I loved the cranberry color with the scalloped edges and always looked forward to slipping into these after a long day of hiking. Would recommend.

These bottoms are wonderful for pajamas here in the cold north! I buy a size up for extra comfort, but it appears that they are true to size. Definitely not as warm as Capilene 4 and a nice midweight with a low profile.

I'm always cold when skiing, and the previous base layers I tried had leg bands at the bottom that were very uncomfortable under ski boots. Following a recommendation, I went with the Capilene 3s, with a fleece layer before the shell. They were great! Very comfortable, moved with me but didn't ride up, great flat seams, and best of all toasty warm! Worth every penny!

These pants are nice and light enough under clothing. Only thing I wish they had was ribbing at the bottoms to help them stay down.

My wife loves the fit, and loves how warm she is skiing now. They seem to fit a little larger but they are super thin for just Cap 3. Cap 4 seems to be pretty thick and Cap 2 about the same thickness but not as warm. Warning, your wife might start complaining about being warm since she wont worry about being cold!
