Designer Bums

Swim Onesie ~ Sunny Blooms

$39.95 $54.95

Designer Bums Unisex Onesies are protective swimwear that is breathable and comfortable to wear whilst still providing protection against UV rays. You can expect your Designer Bums Onesie Swimwear to feel soft and silky against your little one's delicate skin.

Designer Bums Onesie Swimmers feature long sleeves and short legs to provide as much coverage from the sun as possible whilst giving your little one comfort and freedom. A zipper opening at the chest and snaps inside the legs make this onesie easy to use and allows for easy access to your swim nappy for changes. There is no need to pull your  baby swimwear on and off whilst dealing with a soggy swim nappy. 

Designer Bums Swimwear is made from Repreve, a sustainable material made from ocean and landfill bound plastic bottles. Each piece features our signature hand-illustrated artist designs created exclusively for Designer Bums.
