ZIGJOY Shark-Fin Transition Swaddle - 2.5 Tog Fleece Sleep Sack for 3-6 Months

Meet the ZIGJOY Shark-Fin Transition Swaddle

Designed to ease the shift from traditional swaddling to independent sleep, this fleece transition sleep sack hugs your baby in warmth while giving tiny arms freedom to explore and self-soothe. The shark-fin shape mirrors a natural transition, so your baby can reach out, root for comfort, and gently practice rolling as needed.

Warmth and comfort for cooler nights

With a 2.5 tog rating, the outer fabric is 100% flannel — soft to the touch and cozy against delicate skin. It is intended for cooler temperatures, roughly 61-68°F (16-20°C). The suit is machine washable at a low temperature for easy care, helping busy parents keep laundry simple while preserving shape and softness over time.

Designed to support safe transition and self-soothing

The shark-fin transition swaddle uses sleeves to gently regulate arms while still allowing the baby to reach for a finger for soothing. The tightened waist and smooth 2-way zipper create a secure feel when wrapped, which may help reduce wake-ups and support longer stretches of sleep for both baby and caregiver.

Growth-friendly fit and mobility
