I have to disagree with the first review. I found these wristbands to be very absorbant and very resistant to losing their tension. It seems as if Nike made it a mission to produce wristbands that could take the proverbial licking and keep ticking. Past Nike wristbands were models of slackness and poor durability. This latest round seems to answer the questions and doubts.
I like the double wide size, but the material used is inferior. I know that they will stretch and not hold their shape, as did some other Nike wristbands I got a year ago. Meanwhile, I bought a pair of Adidas reversible wristbands a few months ago, and they are far superior.
