Review: Warm, Snug, and Better Than I Expected - I grabbed these WEERTI thermal long johns for cold days and they’ve honestly become my default base layer once the temps drop. The inside fleece is very soft and cozy, and the fabric has enough stretch that I can move around, bend, and sit without feeling restricted or like the seams are fighting me. They fit close to the body, more like a second skin, which helps keep warmth in, but it also means you may want to size up if you’re between sizes or don’t like anything too tight. I’ve worn them under jeans and work pants outside and also just as loungewear at home, and they’ve kept me warm without getting overly sweaty thanks to the moisture‑wicking fabric. ​ They’re not perfect, though. The waistband and cuffs can feel a little snug after a full day, and if you run hot or spend a lot of time indoors, you might find yourself getting warmer than you’d like. The material is synthetic, so if you’re used to merino wool base layers, this won’t feel as “premium,” but for the price it’s hard to complain. Overall, these are a solid, comfortable option for everyday winter wear, especially if you just need something dependable for walking the dog, commuting, or working outside in the cold. ​
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!

### ⭐⭐⭐⭐⭐ Feels good, nice and warm
*by P***Y on February 4, 2026*

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.
