Olive green nylon cap with a mesh back design for excellent breathability. - Brand: milestone - Color: Olive Green - Material: Nylon - Design: Mesh Back Thank you for viewing. This is a running cap from Milestone. It's the first model, and the design of the underside of the brim, which is not found in current models, is a key feature, making it a cute model. The front logo is embroidered, and the "81" on the back is a sewn-on embroidered patch design. The tag printing has faded after several washes. There is some overall wear and tear, but it can still be used. Please understand that this is a used item and purchase accordingly.
