We made these for our team, but we needed to order at least 500 caps so the extras are reserved to give to our customers for special occasions. It's a simple cap, made from a cotton twill fabric and lined with a light-weight mesh. A double soft elastic band keeps the cap in place at all times and makes it feel comfortable to wear over long periods of time. The brim of the cap has a hidden reflective panel for safety, and a smooth velcro strap allows you to adjust the size for a snug fit.
