These are a great brand of undershirts. My fiance has worn them for 2 years and I love how they wash so well. You can bleach them every wash and they stay exactly the same in terms of fabric quality. They are a thicker, premium type fabric but not too thick and definately not warm. I know this because I wash them and know how long they've lasted and how much he grunts and groans if I buy different brands, but also because I like to swipe them to wear around the house on a weekend or as an occasional gym shirt when I've forgotten to put the fitness clothes in the laundry. Definately worth the money.
