It's a t-shirt. It's a baselayer. It's your new favourite hiking shirt. The adidas Terrex Multi Half-Zip Tee is made with AEROREADY to manage sweat and keep you dry and comfortable through any effort. Offset shoulder seams reduce chafing under a backpack, and an extended back hem adds coverage where you need it. Made with 100% recycled materials, this product represents just one of our solutions to help end plastic waste.
