The band worked just great. Cycling in very hot temperature near 36oC climbing big mountains for multiple days. Although I was sweating a lot I never had any sweat in my eyes or in my sunglasses. My husband profusely perspired so the result was not as convincing.
I love your products. I've purchased just the band before this but this time I ordered the skull cap. It's awesome. I've always wore a cycling cap along with the band to keep the sun off the top of my head because of me being bald. It's great now I don't have too. They really are worth it!
