Calidum 5 Panel Hat Size:One Size features an open QuickSlide topThe Calidum is a little different. We took the classic five panel design, then made it with the same performance structured mesh we use in our Konseal climbing harness. The result's a durable, breathable cap that works anywhere pushing it on the trail, hanging out at camp, and resupplying in town. The material's stretch forms to fit, and the back secures with a TPU strap and buckle. ______________ Weight: 52g 1. 8 oz Activity: Hiking Trekking Running
