What the AI looks for in Baby Girls' Swimwear Sunsuits
- UPF rating
- Look for a labelled UPF 50+. A sunsuit exists to replace most sunscreen on infants.
- Coverage
- Long sleeves; full-length or knee-length legs. Arms and thighs are the exposed areas a one-piece misses.
- Closure
- Choose a front zip running to the crotch or leg, or crotch snaps. These let you change a diaper without stripping the whole suit.
- Warmth
- Thin fabric for hot sun; thicker or neoprene-style for cool water. Babies chill quickly in water, but overheat on the beach.
Brands that matter
- Splash About: Baby swim specialist.
- Coolibar: Sun-protective clothing brand.
- SwimZip: Zip-front sunsuits.
- UV Skinz: Kids' UPF swimwear.
What to avoid
- Thick neoprene-style suits on hot beach days.
- Pullover sunsuits with no zip or snaps for babies in diapers.
