Review: Sooo Comfortable, fit great, and work for really cold weather! - These WEERTI thermal base layer underwear is by far the best base layers I have ever purchased. Perhaps they have been too good because I always wear the top under my flannels as I work in an unfinished part of my house that does not have central heating for a few days a week. I meant them to be for running outside in the mornings, but they are just so comfortable. Both top and bottom are super comfortable and super warm. I saw a review when deciding to purchase these around a year ago that complained about the material balling up from the fabric w/ wear and wash. I have seen that too and I don't care because they are sooo comfortable and get the job done whether for running or athletics outside (snowboarding) or for just being around the house w/ the heat turned down low. Thanks WEERTI!
Review: Feels good, nice and warm - Best thermals I've owned. These are like a second skin. I don't feel them but I notice the warmth. Lightweight and with the fleece lining, no more itch from waffle or fabric like the others I wear. I Bought 1 pair to check out, just ordered 2 more sets. I did order a size up and glad I did. fit perfect.

### ⭐⭐⭐⭐⭐ Nicely does the job!
*by C***M on January 21, 2026*

I am 6'1" and 245 lb and got myself 3XL (XXXL) and fit perfect. Feels perfect and also does the job perfect for me. Please don't hate me but I am a CA bike rider and for us in here when weather goes below 50F we feel like exploring Antarctica on our bikes. I've worn these during a trip here in CA and for a few hrs I was exposed to 42F weather and didn't shiver nor sweating. But I was comfortably warm under just atypical motorcycle jacket (not a very high quality) and a thin layer of turtle neck made out of a light material. So it may not be the best one in the world but definitely the best one for the money! Again, if you're riding in North Dakota winters it may not be sufficient for you but it is great as a base layer that helps you to stay warmer in 40F kind of weather at 70 mph on a bike!
