Straight from the archives, the inspiration for this adidas adventure runners cap is clear. while the hat doesn't require clocking miles, it is still about absolute comfort. the mesh sweatband and breathable mesh panels on the sides make that clear. an adjustable bungee on the back lets you find the perfect fit. made in part with recycled content generated from production waste, e.g. cutting scraps, and post-consumer household waste to avoid the larger environmental impact of producing virgin content.
