Strap Size Guide
90% of ZOX customers wrists fit nicely into a Medium. If you're buying for a kid or someone with slim/petite wrists, get them a small. Average wrists fit nicely into a medium. Larger wrists will be more comfortable in a large. All wristbands stretch from the original size to fit the wearer. If your ZOX is a bit too tight, don't be afraid to give it a good stretch or two.
Our new kids sizes will fit most kids 3-9. We've even had some adults tell us the kids size fits perfectly, so as long as your kids wrists are small, it should continue to fit.
