For years, companies have claimed that their moisture-wicking materials would make you feel cooler & more comfortable. This one actually does it! I wear these shirts to bed every night now, and for the first time, I don't wake up sweaty! I wear them in the house & on the go, and they keep me cool & dry. BTW, the daytime temps have been in the upper 90's for the last 2 weeks, but these shirts have still kept me cool. Also, after the first wash, they are very soft, inside & out. Highly recommended.
