Our Dillos Sun Onesie is built for hot days outside. The soft and breathable knit fabric provides UPF 50+ sun protection through its construction, not sprayed-on chemicals. Mesh underarm vents release heat and moisture to help prevent overheating as the day warms up.

Designed with parents in mind, a full-length front zipper makes changes quick and easy, and the built-in hood and flexible visor stay with the suit, without the endless fall-off, pick-up routine of a hat.
