ZOX are water-friendly! We have worn them in the pool, ocean, and even scuba diving! Even after taking a dive, their colors remain vibrant and awesome. However, we recommend ordering ZOX that fit snugly to ensure long-lasting wear.
Once in a while we see ZOX that are in water non-stop or ZOX that are too large get a little warped, as elastic tends to do over time. Though unless you're a fish you probably have nothing to worry about!
