Review on 👕 LAPASA Men's Thermal Underwear Top: Fleece Lined Long Sleeve Shirt - Light, Mid, or Heavy Weight (1&2 Packs) - Thermoflux M09/M55/M26 by Reginald Ward

I liked them so much that I ordered another pair in white. They're thin and breathable, but nice and warm when used as a base layer. They may not seem warm on their own due to the polyester fabric, but under another shirt (like the one I use) they are surprisingly warm for their weight. The product is very light, stretchy and actually has an inner fleece fleece that feels comfortable. This is not a two-layer polyester thermal underwear, just one layer with a brushed underside. I bought my normal size and it fit perfectly, the arms were definitely long enough to reach my wrist and stretchy enough to be snug without restricting. It's also worth noting that my neck openings were a normal girth and not very wide, as some others have said they may have improved on this with these later runs. All in all a great, thin and light thermal underwear that works great as a base layer. I would definitely buy again if needed. PS; They are also machine washable and machine dryable, but the label says they can be hang dried.
