The T-shirt was true to size and of good quality. I only gave five stars because I believe the price is a little much for this. I’m saying this about the price, because the claim that it is cooling has never worked for me yet and I wash them exactly as per instructions not to use fabric softener nor dryer sheets. I hang them up to dry and wash them only in cold water and my delicate wash cycle and I only use natural detergents because of allergies, so it doesn’t get exposed to toxic chemicals at all, not even perfumes or scented body lotions. Maybe it is just my body that is unable to feel the cooling effect, but I really doubt that since I do have a different item with the same claim and that I can actually feel it as soon as I start to sweat.
