Eco-friendly Supersoft Fabrics & Clever Features 

Every MORI baby romper, including selected baby cotton rompers and one-piece outfits, is designed with comfort at its heart. Our collection includes our signature blend of sustainably sourced bamboo from viscose and organic cotton, silky-soft modal made from sustainably sourced beechwood trees, breathable ribbed fabrics and more organic materials. Each fabric is carefully chosen for its softness, breathability and durability, helping little ones stay comfortable whether they’re sleeping, playing or exploring.

Our baby rompers for bedtime are packed with thoughtful features parents love. Many of our award-winning baby zip rompers feature our signature Clever Zip, a two-way zipper designed to make diaper changes quicker while helping keep baby cozy and settled. Selected newborn styles also feature integrated scratch mitts to help prevent little ones from accidentally scratching delicate skin during sleep, while our footed rompers are thoughtfully shaped to support healthy hip development with plenty of room for natural movement. Gentle seams, soft cuffs and premium finishes help create a cozy, comfortable night’s sleep.

Our daywear rompers, overalls and jumpsuits are designed for every wiggle, crawl and first adventure. Practical snap fastenings at the crotch make diaper changes quick and fuss-free, while adjustable shoulder straps on selected overalls provide a comfortable fit as little ones grow. Relaxed silhouettes, soft stretch fabrics and roomy shapes allow babies to move, crawl and explore freely without feeling restricted, making them easy to layer throughout the seasons and comfortable enough for all-day wear.
