Unnivoll Fleece Baby Sleep Sack 18-24 Months – 1.0 Tog, Long Sleeve, Two-Way Zipper

Cozy, Safe Sleep for Toddlers

Meet the Unnivoll Fleece Baby Sleep Sack in a grey and white dinosaur print. Designed for active toddlers around 18-24 months, this wearable blanket blends a soft, skin-friendly texture with a secure silhouette to support restful nights without loose blankets around tiny limbs.

Safety comes first. The sleep sack uses high-quality 100% polyester microfleece that offers a gentle touch against delicate skin. It is certified by the Consumer Product Safety Commission (CPSC), highlighting a focus on a secure sleep environment for growing kids.

Why this sleep sack stands out

With a 1.0 tog rating, it is well suited for indoor temperatures around 68-75°F (20-24°C)—typical for spring and fall. The plush interior against the skin and the breathable outer layer help manage moisture as your child moves through the night, promoting a calm sleep routine.

• Two-way zipper for easy nighttime diaper changes; a protective zipper cover shields the chin from scratches.
• Roomy enough for kicking and wriggling, yet designed to stay in place for secure sleep.
• Long sleeves add warmth and freedom of movement, supporting comfortable sleep through cool nights.
• Two-pack convenience means you can rotate outfits while one sleeps and the other is in the wash.

Care and sizing are straightforward. The sleep sack comes as a two-pack and is machine washable and dryable on low heat for busy families. Four size options (S, M, L, XL) cover a growing child; refer to the size chart and measure height and weight for the best fit.

• Four available sizes help you find the right fit as your child grows.
• Low-heat machine wash and tumble dry keep fabrics soft and easy to care for.
• Wearable design with a playful grey and white dinosaur motif adds a bit of bedtime charm.
• Made from comfortable microfleece that feels gentle against skin and stays breathable overnight.

In real life, this sleep sack shines during bedtime routines at home, weekend trips, or naps away from familiar surroundings. The design aims to support a calm, independent sleep ritual by offering warmth, coverage, and a secure sleeping layer. While each child is unique, many families appreciate the simplicity of a warm, snug layer that helps maintain a consistent bedtime environment.
