TSLAMen's Thermal Underwear Pants, Heated Warm Fleece Lined Long Johns Leggings, Winter Base Layer Bottoms

Bought true to my size, medium. I am 5'6" and 165 pounds. I normally by 30" X 30" pants. They fit like a glove. I bought a second pair immediately. I have not washed them yet, probably will not put them in the dryer. I love everything about this brand. My second favorite is Nike, but Nike lacks a true pouch with their products. These have an ergonomic fit for the boys, and are very comfortable. The waistline fits good, and will not be sticking out over my pants. Most long underwear seems to reach my belly button. They are reasonably warm, and as it hasn't dropped below freezing the real test for that is yet to come. I could have another inch or so to my waist and they would still fit, although compression would increase. If you are up to a 32" waist get medium, any bigger would be large. I may have to order a third set, I already have white and dark grey. This brand really is awesome on the fit and quality of their products. Thanks Tesla, your brand fits me. (They will not fit every body as well-that is just clothing)

Just like other TSLA base layers, will made and comfortable with good warmth/weight ratio

Lovely product, I’m definitely a fan of them. The only reason I didn’t give them 5 stars is that they are a little tight. I’m a runner and so maybe my quads are a little thicker than normal but my waist is about a 29 and fit my waist quite snug. However, they can be a little harder to get on as they are very tight around my quads. Perhaps I should have ordered a medium which would normally be a little big but in this case they probably would have for a tad bit better.

Got these for my husband to wear under jeans on the motorcycle to cut down on the chill during his long commute to work. The fit is perfect, nice stretch to them, and he especially liked that they're smooth on the outside making it much easier to get jeans over top. He said they're a little warmer than his standard Hanes thermals so a definite win!

Wore these deer hunting this year. Worked very well. Quite pleased.

Waist band is a bit thick similar to a short's elastic band

Love my space cadet husband in these. Fit tight and keeps everything warm and toasty.

This undergarment works well in keeping me warm. What's great is the slit that allows me to not have to lower my pants and undergarment to go to the urinal, unlike sweats that have no opening.
