Our Analysis

Here is the fun-in-the-sun outfit that will protect your baby's entire body from harmful ultraviolet sunrays. Made with their proprietary Sun Protective aqua SUNTECT® Polyester (with a rated UPF of 50+), Coolibar has produced a very stretchy yet comfortable outfit that not only keeps the sun and both salt and chlorinated water from damaging your child, but itself as well; it's even easy to put on and take off with its front snap neckline and snap-close bottom for quick diaper changes.

We are especially impressed with the aqua SUNTECT® fabric for its UVA- and UVB-protective, lightweight, quick-drying and long-lasting qualities. As baby's face, hands and feet are still exposed to the sun when wearing this full body suit, we recommend using toxin-free sunscreen, sunglasses and a sunhat for further protection.

The Coolibar UPF 50+ Kid's Infant Beach Romper is available in three styles (Turtles, Flora Lei, and Tropical Violet) and in four sizes (6, 12, 18 and 24 months).


The most commonly cited likes for this product are:

  • Provides excellent sun coverage from ankles to neck
  • Protects entire body (except hands, feet, and face) from sunburn
  • Comfortable
  • Easy to put on and take off
  • Adorable


User reviews frequently note these disadvantages:

  • Sizes run a bit small for some
