These items typically range from infant to kids sizes. Infant sizes often use numeric codes (for example, 66 = 3–6 months up to 90 = 12–24 months) or month ranges (9–12, 18–24 months). Some costumes are sized for children (about 5–12 years). Activity jumpers are generally intended for babies around 6 months and older.
Infant rompers and coveralls are commonly made from cotton or organic cotton. Costume and faux-fur jumpsuits are usually 100% polyester. Door-mounted activity jumpers list structural components such as steel and plastic, with fabric parts often polyester.
You’ll find a mix of pull-on styles and garments with front button-down closures, crotch snap closures for easy diaper changes, and zippers on some jumpsuits (costumes often use back zippers).
Rompers may come with matching accessories such as a headband. Costume jumpsuits commonly include attached mitts and matching shoe covers as part of the set.
The door jumper is intended for babies who can hold their head up, with a suggested starting age of about 6 months and up. The product lists a maximum recommended weight of 26 pounds.
There are bear coveralls and union suits labeled as made from 100% organic cotton. These items are described as soft and gentle for delicate baby skin.
