For size reference, I’m 5’3”, generally wear Small / size 2 or 4 depending on brand, style, etc. Bought a S in this and it fit fine. Definitely not ultra snug, rather pretty loose. At first I was really disappointed, thinking that as a base layer it was supposed to be like 2nd skin, and considered returning it but didn’t have time before leaving for a trip in a couple days. In the end, I’m happy about the fit. I think an XS would’ve felt too constrictive and the waistband definitely too uncomfortably snug. I had no trouble slipping on some jeans (regular/straight fit, not skinny leg or anything) or some rather thick/heavy-weight leggings over these - although I had to do a little tugging and pulling on these bottoms when trying to slide the leggings on to get the bottoms to stay in the proper position. The material is extremely thin, like hosiery. I wondered how it could possibly do its job of keeping me warm but it did its job to the fullest. Plus although it may have the appearance and thinness of hosiery, fortunately it FEELS nothing like hosiery. I wouldn’t have been able to tolerate that feel. But these bottoms are wicked soft and smooth, not at all scratchy or having that wire scouring-pad feel of hosiery. I also really liked that this was thin enough to take up very little space for packing as we were trying to travel light. I’m really glad I decided to keep it. The bottoms turned out to be fantastic for a cold weather vacation, worn as a base layer. I was happy as a clam wearing them almost every day during a 9-day trip in 40-45 F temps. I’ve always lived in balmy FL and have no clue how to dress properly for cold weather, but staying warm was a big deal for me to be able to enjoy the trip so I was really putting a lot of confidence in this article of clothing and it actually came through! It’s only a base layer - and a lightweight one at that - so to reiterate, naturally I had jeans or heavy leggings over it but honestly I think it was the base layer that made all the difference in being able to stay warm. I’m thrilled that it worked out. FYI I ordered the matching top (Terramar Women's Thermasilk Pointelle Scoop neck) with the same satisfactory result, as well as a MIDweight base layer set (32Degrees Women's Heat Thermal top and bottoms) for the slightly cooler days (30-40 F).

I got these as a space-saving option for travel and I think they’re going to work well. They are very thin, but seem to make a noticeable difference in warmth under pants. The fit is perfect. Read more

Great long johns! Just bought this to replace a pair that are falling apart after after 15 years! Very light and thin, can wear under regular pants, even slim jeans. Tight at legs but not at waist and hips: I am not curvy but straight waisted, and I could see these fitting either. Bought medium for size 10, not too loose but these could definitely fit a bigger person. Comfortable wide waistband fits high, a little like granny underwear, but much more comfortable for all day wear than tights. Perfect for everyday wear with normal clothes, walking around and in a warm office. For just outdoors I wear a thicker pair of patagonias under all weather wind pants. Read more

I bought two sets of long underwear for the season, these in oatmeal heather size medium, both top and bottom, and the Cuddl Duds Women's Thermal Long Sleeve Top & bottoms. This is a pretty classic set of long Johns. Like them a lot. I wear them under waterproof Patagonia pants out rowing on Gloucester Harbor. I am warm, cozy, and dry in them. I've already washed and dried them and they didn't seam to shrink. Folks' reviews complain of their being too thin and running. I am not experiencing that issue with these. They're supposed to be lightweight. And if yours ran, maybe you're running something scratchy along them. They shouldn't run. These are very seathrough. So they've got a sexy appeal to them too. So if you're on a little winter holiday getaway with your sweetie, these are kind of sexy in an unexpected kind of way, but maybe only would be considered sexy to folks who love winter outdoor sports and winter indoor recreation by the fireside.

I bought these because I probably wear what people think is my uniform. I don't dress all that differently from one season to another, except short sleeves/long sleeeves and sweaters. I bought these to fit under my sheer black pants for insulation. I wear the same draw string black pants - I have many pairs, for all seasons. I find these "Thermasilk pants" very comfortable. They're light enough to breathe and I don't feel like I'm wearing anything heavy or restrictive beneath my main black pants. They give enough protection from the cold and coverage to be warm and comfortable inside or out. Because they are light weight, if you don't want to buy more than one, they are easily hand washed, wrung dry and dry overnight. Give them eight hours to hang dry. I've bought two pairs so far and I highly recommend them. Read more
