Jellymoni Baby Sleep Sack 12-18m – 3-Pack, 100% Cotton Wearable Blanket

Meet the Jellymoni Baby Sleep Sack, a breathable, softly knitted wearable blanket designed for infants and toddlers. Made from 100% knitted cotton, this sleep sack feels gentle against delicate skin and stays comfortable through the night. Independent safety checks help ensure a trustworthy build while maintaining a lightweight, cozy feel.

In addition to comfort, the design supports growing babies with a roomy hip area that allows legs to move naturally. A practical two-way zipper opens from the bottom for fast diaper changes and from the top for easy dressing, complemented by a top zipper garage that protects tiny faces from chafing. The set comes in a practical 3-pack, covering multiple growth stages with four size options—0-24 months combined across newborn, S, M, L, and XL choices—so you can find the right fit as your little one grows.
