Infant Green Swimsuits

Most infant swimsuits now have UPF 50+ fabric that blocks about 98% of UVA/UVB rays, so check that rating on one-pieces and rash guard sets. Brands like Gerber Childrenswear offer UPF 50+ prints in quick-dry nylon-spandex blends that hold up to frequent washing and sun exposure.

For cooler pools, a neoprene wetsuit with integrated swim diaper and thermal insulation will keep an infant warmer than thin swim fabrics. The Splash About Happy Nappy Wetsuit is designed for 0–3M babies and pairs neoprene warmth with a built-in diaper for containment.

Size infant swimwear by your baby's age and how much room you want to allow—sizes run from newborn (0–3M) up to 24M. Prioritize easy-entry zippers, snaps, or poppers plus stretchy designs with adjustable straps or elastic waists to handle growth and active movement.

Two-piece tankinis and bikinis are fine for casual splashing and warm-weather swimming, especially in quick-dry nylon-spandex blends. For more active play or longer sun exposure, consider switching to a one-piece or long-sleeve rash guard with UPF 50+ for better coverage.

Wetsuits with integrated swim diapers and popper or snap closures are designed to contain solids while simplifying changes. Also look for double-lined panels and reinforced stitching to keep the suit durable through chlorine exposure and frequent washing.
