Trail-T Solar is a close-fitting performance T-shirt for exposed trail runs. Its engineered polyester knit uses On DryTec to move moisture and dry quickly, while UPF 40+ protection reduces the load from strong sun.
A slightly higher collar and longer sleeves extend coverage without turning the top into a heavy layer. Underarm gussets and forward-set side seams follow the upper body through steep climbs and technical movement.
The seam placement is designed to limit friction beneath a running vest. A reflective mark remains visible around the vest itself, keeping the detail relevant after the light changes.
