Unnivoll Fleece Baby Sleep Sack 1.0 Tog – 12-18 Months, Yellow & White Elephant

Soft, Safe, and Simple Sleep for Your Baby

Meet the Unnivoll Fleece Baby Sleep Sack, a cozy wearable blanket designed for infants and toddlers in indoor settings. Crafted from 100% polyester microfleece, it offers a gentle touch against sensitive skin while keeping little arms free to move. This model is certified by the CPSC, supporting a secure sleep environment and peace of mind for busy parents.

What makes it a practical choice

The 1.0 tog weight pairs nicely with typical indoor temps of 68-75°F, making it ideal for spring and fall nights. The mix of plush inside and breathable outer fabric helps your child stay warm without overheating, while still allowing moisture to wick away for dryness through the night.

• Two-way zipper for easy diaper changes without fully undressing, with a zipper guard to protect delicate skin.
• Sleeveless design to promote free arm movement and reduce overheating risk.
• Roomy hip area supports natural leg movement and comfortable positioning as your baby grows.

Two-pack convenience and sizing

This set includes two sleep sacks in a practical two-pack. Choose from S (0-6m), M (6-12m), L (12-18m), and XL (18-24m)—size by your baby's height and weight using the included size chart.

• Easy care: machine washable and low-heat dry for quick refresh between naps.
• Trusted safety: the fabric is skin-friendly and easy to maintain, designed for extended wear as your baby grows.

Care and use tips

To maximize comfort, ensure the sleep sack sits comfortably around the shoulders and hips. The two-way zipper makes middle-of-the-night changes smoother, while the chin guard minimizes contact with the zipper pull.
