This is a Workman sports cap. The color is gray, and it's a free size suitable for 55-60cm. It's made with COOLMAX, which has excellent water absorption and quick-drying properties, and I think it's comparable to summer running caps from sports manufacturers. I've used a different color, and I think the size is similar to a L size running cap from Mizuno or Asics. It's a new item with tags, but it has been stored at home, so please understand this before purchasing. It will be folded and packed small, so please be aware of this as well.
