These shirts are a very good buy for the price. Unlike all cotton undershirts, this blend won't shrink and is very soft. Overall construction is very good as well. I always wear undershirts, even in the summer, and these aren't any warmer in hot weather than the all cotton shirts I've worn. For washing, I use the gentle cycle with other white items. Drying is also done on the gentle/delicates cycle and they dry very quickly. I've bought several packages and will definitely be buying more. I'm glad to give these five stars.
