Unnivoll Fleece Baby Sleep Sack 18-24 Months – 2.0 Tog, 2-Way Zipper, Grey/White Dinosaur

Cozy, safe warmth for every night

Meet the Unnivoll fleece baby sleep sack designed for growing toddlers. Crafted from soft 100% microfiber polyester, it offers a skin-friendly feel that little ones love. The fabric balance is ideal for indoor warmth, with a 2.0 tog rating that suits fall and early winter temps around 64–70°F (18–21°C). The exterior fabric is gentle to the touch, while the interior fleece locks in warmth so your child stays cozy as they sleep. Certified by the Consumer Product Safety Commission, this wearable blanket is built to support a secure sleep routine without limiting movement. The design is roomy enough to accommodate kicking legs and free arm movement, while still providing a snug, reassuring layer of warmth.

Smart design for safety and comfort

The sack features a premium smooth two-way zipper that makes diaper changes at night quicker and quieter. A zipper protector at the top shields the baby’s delicate chin from scratches, and the long-sleeve cut helps keep arms warm without restricting motion. The roomy hip area supports healthy hip development and reduces the chance of the sack riding up, so you can rest easier knowing your child stays covered as they drift off to sleep.
