I was skeptical at first because I didn't see the zipper close in any product photos or reviews. A zipper is more like a plastic bag that you line up and squeeze until it snaps into place. I didn't like it at first, but when sealed it holds tight and doesn't spring open when you squeeze the sides of the case. I put some tissues in the case to test it out before putting my phone in. Have lifted it 8ft many times without another strap. I tied him to the pool pole and left him at the deep end overnight. More than 12 hours on the pool floor and no traces of water on the towels.
