My head size is 23-5/8" (60cm) and I regularly wear size up 7 - half brimmed hats, and after adjusting the strap this hat fits comfortably with little headroom, for someone with a large head or thicker/longer hair it might be a bit too tight. Both colors (khaki, navy blue) are a bit washed out in the area photo in of the listing - this is how they look in bright light/sunlight, but in more subdued light both colors are darker and the khaki has a noticeable green/olive tinge. In the photo I posted I used my olive field jacket as the background because most people have seen this color and can use it for comparison to better understand the true colors of the hat. Lightweight and comfortable, the hat should be a good alternative to fedoras and brims be / or wool hats in the hot summer months. That being said, the cotton material absorbs water like a sponge, so this cap probably won't work for those who want to use it to keep their head dry during a downpour, although I suspect it might be 'waterproof'. Yes, that's my only "complaint" and I think it's minor.
