This baby one-piece is the dream combination of a t-shirt and one-piece. We spent two years in development until we created our incredible Float Jersey™. Super soft and with just enough stretch so your baby feels snuggled, while retaining durability through countless wash and dry cycles. And we made sure our perfect baby one-piece had snaps in all the right places (including the interior, for extra secure fit), making changing incredibly fast and easy.

Materials: 100% organic cotton. Double knit jersey

Care: Machine wash and dry

Fit: We believe in making clothes that last. Our designs have an innovative flex fit, meaning they can withstand growth spurts so you can buy less and wear them longer. Every Oso piece is preshrunk, so you never have to size up again. The size you order is the size you get. See our Oso & Me  to get the perfect fit!
