Unnivoll Baby Sleep Sack 18-24 Months - 100% Cotton, 0.5 TOG, 2-Way Zipper | Blue Dolphin

Soft, breathable comfort for growing toddlers

The Unnivoll Baby Sleep Sack in blue dolphin is meticulously crafted from 100% combed cotton, delivering a luxuriously soft touch against tiny skin. The fabric breathes naturally, helping your little one stay comfortable through the night, while a lightweight 0.5 tog keeps warmth steadier in typical nursery temps. The gentle print adds a calm, playful note to bedtime, making the sack feel like a familiar, comforting layer rather than a bulky blanket.

Grow-with-you fit for babies and toddlers

Designed to grow with your child, the sack offers room to kick without the fear of slipping off. The sleeveless cut reduces overheating and supports free arm movement, helping your little one feel secure while staying cozy. Four size options cover babies from 0 to 24 months, smoothing the transition from infancy to toddlerhood.

• Safety-first design certified to meet CPSC guidelines for a safe sleep environment.
• Easy diaper changes with a full-length 2-way zipper and a protective zipper guard.
• Durable, machine-washable cotton that tolerates low-temperature drying without distortion.

Care you can count on and warmth that lasts

Care and longevity are built into the fabric. Pre-washed technology reduces shrinkage by about 50 percent, helping the garment hold its shape after repeated washes. The cotton remains soft after machine washing and low-temperature drying, keeping bedtime routines simple and predictable.

• Pre-washed cotton reduces shrinkage and maintains fit over time.

It offers a breathable layer for warmer months and a snug, secure fit as the room cools, and balances warmth with comfort without bulky blankets. While individual results vary, many families appreciate the ease of diaper changes, the secure fit, and the familiar, cozy cotton garment your child can wear night after night.
