The Gregster Men's Tank Top for sports and running comes from a private brand of Amazon. The appearance is very good and you will find no annoying label in the neck. The seams are great and you can feel indeed quite on the skin, but they do not chafe uncomfortably. That's a lot of value and makes for great wearing comfort. Normal I wear L or XL and because the shirt should be tight, I've slammed at L. It is somewhat large. But it is not bad. In sports, it was really nice to wear and I want to praise, no label was grinding in the neck again. The material consisting of 84% polyester and 16% elastin, is really very comfortable to wear on the skin. Moisture is never unpleasant and the shirt dries super fast. A really well-made shirt from the Amazon store brand.
