Review (5/5): nice cap, good value
I just took this out of the bag, so as yet I cannot attest to its durability. However it seems well made, and I like that the cap is fairly thin and light, as it will take up very little space in my travel bag. The elastic is about 1/4" wide, feels strong, so it should hold up. I recommend the extra large, as its just the right size for my average size head.
