Unnivoll Fleece Baby Sleep Sack 12-18 Months | 2.0 Tog Wearable Blanket with 2-Way Zipper

Cozy warmth with room to move

The Unnivoll Fleece Baby Sleep Sack is designed for toddlers aged 12 to 18 months. It uses soft microfiber polyester fleece that feels gentle on delicate skin and helps your child stay warm during cooler indoor days. Certified by the Consumer Product Safety Commission (CPSC), this wearable blanket emphasizes a secure, comfortable sleep space while keeping everyday practicality at the forefront.

Smart design for night-time ease

Thoughtful details work together to support calm evenings and easier routines. A premium 2-way zipper allows diaper changes without fully waking your baby. A zipper protector at the chin area minimizes rubbing, while the sleeveless cut promotes free arm movement and helps prevent overheating.

• 2.0 tog warmth targets indoor temps around 64–70°F (18–21°C), ideal for fall and winter.
• Roomy, yet secure fit prevents the sack from riding up, supporting comfortable leg and hip movement.
• Two-pack option provides convenience for busy families and quick outfit swaps.

Practical and easy care

Built for everyday life, the sleep sack is machine washable and drying on a low setting is recommended. The fabric stays soft after multiple washes, helping maintain a cozy feel over time.

• Machine wash cold; tumble dry low for quick cleanup.
• Available in multiple sizes (S, M, L, XL) to match growing children.

How to choose the right size

Measure your child’s height and weight, then compare with the size chart to select the best fit. The design leaves extra room for movement without slipping off, maintaining warmth through the night.

With its combination of warmth, flexibility, and easy care, the Unnivoll fleece sleep sack offers a practical option for at-home use, daycare, or travel where consistent comfort matters.
