Did the job.
I got the white cap. I don't have any other cycling caps in this style, this was just a test run. It fits about like I expected (for reference I wear sm/med 52-55cm helmets). with the bill flipped up, it is a tad tight at the forhead, but not enough it has given me a headache. I got it to try to see if it helped with sweat running into my eyes, and it did help with that on 90-100+F deg days over the summer. Material is somewhat coarse as one reviewer said, but I don't think this was meant to be a high fashion piece made out of space age materials, especially for 8 bucks. I was sweating like mad on my mid summer rides when I was mainly using this - it is fall now and the white material has not stained up any. Should be useful to keep the chill down in cooler temps also.
