KEEP COOL & DRY ALL DAY LONG: Made from sustainable bamboo rayon, the men's undershirt is not only incredibly soft and comfortable, but it's also highly breathable and moisture-wicking, which keeps you dry and fresh all day long.

DESIGN FOR WELL-DRESSED MEN: Thanks to the strong water absorption, the men's undershirt made from bamboo rayon absorbs up to three times more moisture than cotton, which prevents sweat from seeping onto your outer shirt. The appropriate length also ensures that it stays tucked in when you tuck.

YOUR PERFECT FIT, ALWAYS: The men's t-shirt in regular fit with spandex blend provides enhanced elasticity, making it easier to fit different body shapes. Benefit from the strength and low-shrinkage, bamboo rayon undershirt maintains its size and shape after washing and tearing.
