Great product!
Color: Black
Use this under my hard hat to keep from sliding everywhere. I have bought several over the years and this have been my favorite so far. Will definitely buy again.

Good but if the elastic band were wider it would be great
Color: Black
This is a great under helmet or perspiration barrier for the face during heavy spinning workouts. Sadly to avoid an indentation to your forehead, you must wear it inside out because the sewing band is narrow and tight.

Too damn small
Color: Black
Way too small for an adult. It doesn't even fit my 11 year old. Unfortunately I didn't open it immediately or I would have returned it. Now I'm stuck with something nobody in my house can use.

One size definitely doesn’t fit. Otherwise Ok.
Color: Black
OSFM - one size fits most. It should be OSFS - one size fits small/some. Measured my head size and according to their chart I’m l/XL. This cap is tight fitting and gives you a headache after an hour. Otherwise it’s fine. Keeps your head cool, is absorbent and works well under a helmet.
