The fabric is not heavy at all. The white fabric is almost transparent. Expensive compared to other budget tees (horse fee?). The "Tagless" label causes creases in the back neckline. Works little. Very small in the chest, after drying it shrinks even more. Not a "traditional" or "classic" fit. Long torso disproportionate to chest size. I have a 40" chest and a slim build and I find the medium LL Bean t-shirts fit me comfortably. This medium polo was too small but too long - gifted to a 14 year old who wears sizes small and they thought these 'medium' fit well.
