TSLAMen's UPF 50+ Long Sleeve Compression Shirts, Athletic Workout Shirt, Water Sports Rash Guard

I already have several of this brand and just wanted to add a couple more colors.I've found the combination of materials they use is just perfect, very stretchy, but still conforms to your body, resulting in a comfortable wear.However, the ones previously owned were polyester and polypropolene, resulting in a much softer feel to the material, more like cotton, and a bit more stretchiness, guess they don't make them anymore.These are polyester and spandex, with a more nylon feel, and less of an ability to stretch, though still quite good and within an acceptable tolerance.I have several more expensive versions from Under Armor, of a similar design, in the same size, which stretch very little, and fit so tightly I feel strangled, highly-uncomfortable.Under Armor fits you to the shirt, whereas these fit the shirt to you, huge difference!So the Under Armor are now going to Goodwill, since I've fleshed out my collection with the all the colors I need.I highly-recommend these in colder weather, for additional layering insulation, quite thin, and take up litttle space under a long sleeve t-shirt, flannel, sweatshirt, whatever.
