This t-shirt is very light and airy; it feels like you're wearing nothing. I haven't tested it but I can easily believe it just by the feel of the fabric wicks sweat and dries quickly. The patterns are pretty cool too. It's quite pricey for a basic training t-shirt, but if you have the budget, go for it.
