ULTRA-SOFT SLEEP SACK -Crafted with premium TENCEL Modal fabric, Okayinn modal sleep sack redefines baby-soft comfort. Modal's ultra-fine weave creates a cloud-like texture that's even softer than rayon made from bamboo, gently hugging your baby's delicate skin while maintaining breathability for all-night comfort. This hypoallergenic and breathable fabric helps regulate your baby's body temperature, wicking away sweat to create a soothing and comfortable atmosphere for babies' sweet dream.

SOFTER THAN RAYON MADE FROM BAMBOO- We've crafted ultra-fine yarn from TENCEL Modal, which is one of the best modal out there, to create a silky smooth and luxuriously soft fabric that caresses your baby's delicate skin. This fabric surpasses rayon made from bamboo and wool in softness, while also offering superior durability.

SAFE FOR BABY - We prioritize your baby's safety. The sleep sack features a deeper and narrower neckline to any loose fabric that could pose a suffocation hazard. A zipper protector shields your baby's face from scratching. Our breathable fabric reduces the risk of overheating, making it suitable for year-round use. Modal fibers are regenerated cellulosic fibers from natural wood, making it hypoallergenic for babies' sensitive skin.

DESIGN WITH CARE - Our toddler sleep sack are designed to provide optimal comfort for babies and convinience for parents. 2-way side zipper makes midnight diaper change easily. Stretchy roomy leg room allows your baby to sleep in the frog-legged position, move around freely, but cannot be kicked off, so baby stays warm all night and promoting healthy hip development.

MACHINE WASHABLE & GREAT DURABILITY - Our sleep sacks are designed to be machine washable, making cleaning a breeze. The high-quality fabric and reinforced stitching ensure durability, while the extra-long leg room allows for extended use as your baby grows.（Ensure the baby is intended to be dressed in inner clothing before being put into the sleeping bag.）
