These thermal underwear are fantastic. They’re soft, fleece-lined, and do a great job keeping warmth in without feeling bulky. My husband wears them to football games in cold weather and stays warm and comfortable the entire time. They fit well, layer easily under clothes, and hold up well after washing. Definitely a must-have for cold weather and outdoor events.

I'm 5'10" 205 and the Xl fit great and they are warm. The fabric feel really good on my skin. Temp was 40 degrees today and breezy, wore the shirt under a thin hoodie and didn't feel any wind on my skin. Should be great once layered in cold weather. Nice set.

Got these for colder weather and wear under my clothing when walking/jogging outside in 10-30 F degree weather. After about a month and 7-8 uses and washes I am very impressed. They hold heat in great, good material and quality and after some washes they have not had the lent balls attach to it which is always a concern with this type of material. Has not shrank but it does run tight which is what I wanted, as I am 5' 10' 225 and decently muscular and bigger chest and got a XXL. Fit tight in a good way and I had no issues even weight lifting in these. I sweat a ton and these held the moisture and kept me warm when I hit the parking lot at 25 degrees and windy. I will be buying 2 more sets and rotate them so as not to wash this set to death. Very pleased with them, wish they were about $5 or more dollars cheaper as some others but assume they might not have the quality I find with these.

I was very satisfied with the Thermal Underwear from WEERTI. I like them for loungewear instead of pajamas. I selected the grey, because the color selection was limited. I appreciated the size guide that directed me to XXL for a person with a 38" waist. The fit was rather snug, which I like, but for someone who likes a loose fit, I would suggest going up one size. They are very comfortable and are perfect for watching television on a winter's evening

These are great for sub-freezing temperatures. I just wore them to the Patriots game at Gillette stadium where we sat up on the 300's level in the freezing wind. There was a wintry mix with the temperatures dropping down to 15-20 degrees F during the 2nd half of the game, with the "Feels-Like" temperature of 0. That being said, I was super warm and even a little hot with these on as a base-layer. I would say the shirt was a little tight but the pants fit great - then again, as the base layer you don't want these to be loose or bulky, so that may be good. I'm 5'10 200 lbs and I got the Large size.
