I was nervous about leaks at the pool, but the built-in leakproof technology gave me total peace of mind while swimming with my kids. The cap sleeves are a nice touch for extra coverage without feeling restrictive.

The color block design is really sharp, and the cap sleeves give it a sporty look that flatters my shoulders. I wore it all afternoon and didn't have to adjust or tug at it once, which is a first for me.

I feel so much more relaxed at the pool knowing I don't have to worry about leaks, and the cap sleeves actually add a nice bit of coverage without feeling restrictive.
