Kids grow at their own pace and in their own way, so age and size don’t always line up perfectly. Our size chart is a guide, but every little one is unique.

All our swimmers are designed to fit snugly with just the right amount of stretch, so they move with your child and grow with them, without sagging. If you’re ever unsure, we always recommend sizing up, that way, they’ll have room to grow and enjoy their swimmers for longer.

For the Bobby, we suggest sizing up, especially in sizes 1–2, if your little one has deliciously squishy thighs. Comfort comes first, and we want their swimmers to feel as good as they look.
