Review on 🔥 Stay Cozy This Winter with the HEROBIKER Mens Thermal Underwear Set - Skiing Base Layers with Fleece Lining by Marcos Olvera

Irregular quality. I'm 5'9", about 155 pounds and usually wear medium sized shirts and 32x30 pants. I ordered the larger ones as some of the other reviews say they're a little small. I buy them primarily as a top, to wear under my cycling jersey in the colder months so I'm looking for a very snug, slightly compressive fit.When I tried on the large set the top was fine.Shoulder/shoulder area was tight but not tight.The area was a little loose but not too bad.On the body the shoulders were ok but the chest area was a little looser than I would have liked.The problem was with the bottoms, they fit in width but are too long. Also, the bottoms don't have a cutout in the front (I don't really care). Ordered them. When they arrived today, I noticed that the middle one has slightly different material and different stitching. The big one had flat seams. W If there is no extra material on the inside, while the medium is just regular stitching, where there is extra material on the inside, see the pictures for reference. Also, the material on the medium seems heavier/thicker and not as stretchy. The mid-size upper has a tighter fit, as you'd expect. The bodysuit fits me well and is snug to the body, but the arms feel too tight. The bottom was too narrow for me to be comfortable (and still longer than necessary). In any case, I decided to keep the large and bring back the medium because of the stitching and the more stretchy/lightweight material of the large. The pictures show different tags and different sewing styles. Left is large, right is medium.
