  • So comfortable
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: White
I got 3 pair of these. As soon as I opened the first pair I was impressed and knew rifgt away they would be warm and comfortable. I don't know how long they will last but I assume they should be durable as even cheap thermals I bought years ago are still fine. These fit great. And look very nice and kept me warm outside in about 40-50 degrees (F). I will probably buy another few pair so I can use them everyday during the winter months. I got the heaviest weight (thermo flux). I am very happy. ... show more

  • I will be buried in it, it’s so soft
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Camouflage Dark Gray
I’m 5’11 and like 160-165, the medium fits exactly how I hoped it would. Tight enough to be a base and allow extra layers but not restricting so I’ll still be comfortable on my motorcycle. It is so soft it’s like I’m being hugged by a cloud. Edit/update, not only are they comfy but they are effective. Wore them on a ride for the first time, I only had a pair of jeans and a good quality wind proof jacket over top of these, so not much. It was 43 degrees out and I was doing about 85mph on the Highway, which makes it feel more like 30 and it was a bearable ride, which actually says a whole lot about these thermals. Will definitely be getting more ... show more

  • Very comfortable, and cozy
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Black
I bought the heavy in size M, and I was worried it would not be very stretchy, but it’s very comfortable, warm, and has a great stretch.

  • Mostly satisfied
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Heather Blue
Wasn't as warm as I thought it would be. Still could feel the cold on a cold day. Thought I'd be protected a little better from the cold.

  • Not itchy warm
Special Size Type: Thermoflux 200 Midweight Size: Large Color: Dark Heather Grey
Recommend by a coworker. They are so comfortable ordered large I’m a 35-36 waist they are a just a tiny bit loose on waist but I’m sure after a wash they will fit fine medium may have been fine as well but I’m happy with how they fit. I’ll be ordering more!

  • Winter Warmth
Special Size Type: Thermoflux 200 Midweight Size: Large Color: White
They seem thin but they kept me warm under my pants when it was 37F outside and windy. Fit as expected. Will probably buy more.

  • Comfy and warm!
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Black
I work night shift on a motorcycle and this has kept me very warm so far. I wear this underneath my uniform, so 2 layers, and it’s very warm and comfortable. I’ve actually started sweating when I’m not outside. Highly recommended.
