I own about 20 different all-white tees, and after having experimented with tons of brands, especially in extremely hot weather down in Brazil, I have to say these are amongst my two favorites. The real draws of these CK shirts are their soft feel, light weight, and double-layered v-neck, which makes for a unique, modern look. Besides the Jockey Stay Cool, this is probably the only white tee I'll ever buy again. Oh, and did I mention CK is the best brand to buy for men looking for a true, European-style slim fit. Get some!
