You’ll pull it on in the morning to head to crag and end up wearing it all day long. Comfortable, made to move, and built for performance, the Solarium T-Shirt is one you reach for. Its 160gsm jersey fabric is made from wicking polyester fibres – 52% recycled – and the fit is roomy and free. The bold Bird graphic on the back has a distinctive kaleidoscopic effect and reflects headlamp beams on evening bouldering sessions.
