The TNP T-shirt is built to do one thing—make you better. This T-shirt's lightweight, 4-way stretch construction delivers unprecedented mobility, and Under Armour’s signature HeatGear® fabric wicks away sweat to keep you cool, dry, and light. Optimal seam positioning eliminates potential chafing, and the T-shirt’s anti-microbial technology actually stops odor before it starts. Got a long training session ahead of you? No problem. The TNP T’s got your back.
