The ZIGJOY Baby Swaddle Sleep Sack is the gentle solution for babies moving from traditional swaddling to independent sleep. Crafted from 100% natural cotton with a 1.0 TOG rating, this wearable blanket replaces loose blankets in the crib for a safer sleep environment—no more worrying about your baby getting tangled or uncovered.

The innovative arms‑up design allows babies to self‑soothe naturally by sucking on their fingers, while the covered cuffs prevent face scratching during sleep. The snug waist creates a comforting womb‑like feeling that calms the startle reflex, helping babies settle faster and sleep longer with fewer wakeups.

Practical features make parents' lives easier: the smooth 2‑way zipper enables quick diaper changes without fully undressing your baby, and the machine‑washable fabric stays soft wash after wash. The roomy, hip‑healthy hem allows natural leg movement and kicking while keeping baby securely covered.

Available in two sizes—M (3‑6 months, up to 27in / 18lbs) and L (6‑12 months, up to 31in / 30lbs)—the Shark‑Fin grows with your baby. Choose the size with a little extra room for longer use. Give your baby the comfort of a swaddle and the freedom of a sleep sack, all in one.
