What would you do with four empty plastic bottles? Under Armour decided to make a performance T-shirt out of them. The Waffle Tackle Crew Tee is made from lightweight, 100% recycled spun polyester with a waffle-knit pattern designed to trap heat and keep you warm. ArmourBlock technology helps neutralize odor-causing microbes before there is any odor at all, resulting in moisture transport and maximum scent reduction. Large Under Armour logo across the front. Imported.
