I swim with this belt almost every day. This belt holds to my bodywithout slipping when performing the four swim strokes.I wish this belt had a inner Velcro to hold the inside end to the outer strap keeping the inner end from sliding out, this problem occurs afterthe chlorine has weakened the belt. I had my first belt for 2.5 years,I would recommend replacing the much belt sooner. I love my new replacement belt.
The belt makes it easy to swim laps while you listen to the iPod. Unfortunately the velcro doesn't last as long as everything else about H2O Audio products. The velcro starting coming off after about 2 dozen uses and I had to buy a new swimbelt. Very disappointing.
