Oh Henley! More than a tank top this popular Henley style is made of a cotton/lycra blend for a semi-snug fit. Each piece of clothing is over-dyed to achieve a rich color palate and soft-worn-in-feel. The overall look is complete with 5 front snap buttons that allow you to show as much or as little as you want and spacious armholes for greater mobility. 90% cotton 10% lycra. Made In USA.
