The perfect baby onesie. Soft organic cotton jersey with just enough stretch to give your baby the feeling of being held, but durable enough to hold its shape through repeated wash and dry cycles. This will be your, and your baby's, favorite essential.
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.
