Frequently Asked Questions

Yes. All US and Canada orders over $75 qualify for free shipping with code obiFreeShip. Standard delivery takes 3–5 business days after dispatch. Baby zipper romper outfits can be combined with other Obi items in the same order to reach the threshold easily.

Machine wash cold on a gentle cycle with a mild detergent. Tumble dry low or air dry flat. Both bamboo viscose and waffle knit fabrics in our romper collection maintain their shape and softness with this routine. Avoid high heat, bleach, and fabric softener — bamboo stays naturally soft without any additives.

A standard zip romper is footless and stays that way. Our Convertible Zip Romper is footless in one configuration and can be converted to a closed-bottom footie in another — giving you two formats in one garment. The convertible option is the most popular choice for parents who want versatility across seasons without buying separate outfits.

Yes. Our bamboo viscose is OEKO-TEX Standard 100 certified, naturally hypoallergenic, and free of chemical flame retardants, synthetic dyes, and pesticide residues. It is one of the safest fabric choices available for newborn skin and is used by parents of sensitive-skin and eczema-prone babies specifically for this reason.

Most 6-month-olds fit comfortably in our 6–9M size. If your baby is on the larger end for their age or grows quickly, 6–12M or 9–12M may provide better longevity. Check the weight and height range on each product page — our size chart includes specific measurements to help you choose confidently.
