  • Good athletic fit.
Color: Thermal Fly-front 2pack Dark Grey Size: Medium
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) ... show more

  • Will curl under
Color: Thermal Fly-front 2p Black/ Woodland Sla... Size: Medium
These are GREAT for keeping the cold at bay!!!! Only issue is, unless your built like the guys in the photos, and just like any spandex; the top of the thermals will curl over under any type of belly rolls you might have. I dont consider myself fat by any means, but I have a little belly (dad bod) and I find myself having to pull them up constantly because the tops roll. Buy a size larger if you're like me :) ... show more

  • He loved them!!
Color: Thermal Fly-front 2pack Black Size: Large
My husband goes kayaking on the river and when it starts getting cooler he wears them every weekend! He was so happy I got them for him as gift they fit and work perfectly taking the chill off on the river… A gift I would buy again!

  • Comfortable and warm, but a little big
Color: Thermal Fly-front 2p Black/ Woodland Sla... Size: X-Large
I have a muscular Dad bod, and I'm about 6'1, 265. The extra large is what the size chart suggested, but they're a little long, and fairly loose. The waist band on these could fit a size 55 waist. Get the large.

  • Affordable + Warm + Static + Waist band mark
Color: Thermal Fly-front 2pack Black Size: X-Small
It certainly keep my body warm. My major complains are the static from wearing this and the very "traditional" old style waist band would likely leave some mark on your waist.

  • Cold no more.
Color: Thermal Fly-front 2pack Black Size: 3X-Large
Came in handy more then once on the colder nights when snow / ice was in the area. Through these on back and forth to work for just in case purposes. Glad I did. Hit traffic and was stuck out for 30 extra minutes. To be honest I almost didn't notice because of these and how warm I was.
