The decorative ties actually stay put even after a full day of sand and splashing, which is more than I can say for other sets we've tried. My little one's been comfortable in it from morning swim to afternoon nap, and the lined front gives me peace of mind on windy beach days.
The little knots on the waist stay put even after a full afternoon of splashing in the waves, which honestly surprised me. The UPF 50+ fabric gave me real peace of mind while my baby crawled around the shoreline, and the lined front kept things modest without feeling bulky.
The elastic waist with the decorative ties is what sold me—it stays put even after a dozen sand-and-wave wrestling matches. My little one barely fussed about wearing it, which is a win in my book.
