Does the job

Schickes Muster, wie bestellt, aber für mein Empfinden zu breit, zu auffällig und auch zu labbrig.

comfortable. dries quickly when wet without changing its soft finish. love the packaging & inserts- great place to carry cash poolside without a wallet.

I like the way it doubles as a strap to hang your glasses round your neck, and a strap to keep your glasses snugly on your head - just by moving the slider. Seems expensive for a bit of cotton, but worth it because it does the job well.

They worked well!
