PURFUNMen Women Breathable Cycling Bandana Headscarf Adjustable Sweat Wicking Quick Dry Mesh Head Scarf Wrap Liner Skull Cap

Breathable and stays on. Fit very well

It's a tad big but it's very light weight and breathable material. I would purchase this product again.

real cool looking and covers a man's head!

Update (4/29/23): Both the Klein and Ergodyne, terry cloth styles, are uncomfortably HOT, so won't be using these during warmer months. Where as the others are nice and cool.Summary: I have been riding motorcycles with a full face helmet, daily, for over 30-years. I use a simple handkerchief/bandana between my head/hair and the helmet. Mainly to prevent "helmet head" (messy hair).Observations: There is one big difference between the PURFUN offering, and the other two by KLEIN/ERGODYNE, and it's mainly the material, which is stiffer (similar to a handkerchief) on the PURFUN, and terry-cloth for the other two. Because terry-cloth has no strength, there is an elastic band for both of those. However, the stretchy nature does NOT work at all with my helmet; basically it stretches out of place. Whereas the PURFUN polyester, being stiff, stays in place as I put my helmet on (and can take my helmet off too).Recommendation: I will be using the terry cloth ones with a full trim hard hat, that I use when doing tree clearing work. Both Klein and Ergodyne are construction/professional based companies, so the softer and absorbent terry cloth is well suited for their intended purposes. The polyester PURFUN would not be as absorbent.Conclusion: Rating all of these 5-stars.Related Products:Brand: Purfun, Men Women Breathable Cycling Headscarf Bandana Cap Adjustable Sweat Wicking Skull Cap ~ $84.3 out of 5 stars    119 ratingshttps://www.amazon.com/dp/B07QVBZDYPKlein Tools 60180 Cooling Do Rag, Adjustable Sweat Wicking Skull Cap can be Worn Under Helmet, 2-Pack ~ $10 ($5/each)4.4 out of 5 stars    890 ratingshttps://www.amazon.com/dp/B086TQ9SYYErgodyne - 12478 Chill Its 6615 Dew Rag, Lined with Terry Cloth Sweatband, Sweat Wicking, Camo ~ $74.4 out of 5 stars    11,911 ratingshttps://www.amazon.com/dp/B002M0TYF8

Size on these are difficult to predict, otherwise good breathable fabric.

Very light and cool under my motorcycle helmet; wet it down before you put it on and it's like A/C for your head.

Comfortable and breathable!

It was small for head
