This is a short-sleeved check shirt from Sasquatchfabrix. (Sasquatchfabrix.) The size is listed as L, but it has dropped shoulders and a very relaxed fit. The material is more substantial than a regular shirt, so it's more suitable for the period after the peak of summer heat, rather than mid-summer. There are no noticeable stains, but please refrain from purchasing if you are sensitive to used clothing.
