Freedom in movement is a beautiful thing, and it's what this adidas by Stella McCartney training t-shirt makes possible. It's designed to give you that ethereal feeling of an effortless run — or any medium- to high-intensity training that lights your fire. You'll stay cool and confident thanks to HEAT.RDY technology, enhanced by laser-cut perforations for extra ventilation. Thumbholes in each cuff keep the sleeves snug in place, and a mock neck delivers layering possibilities plus protection against cooler air.Made with a series of recycled materials, and at least 70% recycled content, this product represents just one of our solutions to help end plastic waste.
