Unnivoll Fleece Baby Sleep Sack 12-18 Months | Plush Dots, 1.5 Tog, 2-Way Zipper

Cozy, Safe Sleep Comfort for Growing Babies

The Unnivoll fleece sleep sack blends a skin-friendly 100% cotton lining with soft plush fleece to create a double-layer cocoon that helps your little one feel secure through the night. This sleep sack is CPSC-certified, signaling a commitment to safety while your child naps or kisses dawn with renewed energy.

Smart Design for Busy Nights

Thoughtful details support both baby and caregiver. The smooth two-way zipper makes night diaper changes easier without fully undressing, and the zipper protector at the top guards against chin irritation. These touches aim to keep your baby comfortable and you able to maintain a peaceful routine.

• Two-way zipper for effortless night changes with a chin-friendly top protector
• Double-layer fabric: cotton lining plus plush fleece for a gentle touch
• CPSC certification adds confidence in safe design

Roomy Yet Cozy Fit

The Schlaf Sack is designed with generous room for kicking and movement, yet sleeveless construction helps prevent overheating and keeps arms free for exploration. At a cozy 1.5 tog, it creates a warm, even environment in typical toddler room temperatures.

• Roomy space to kick without being kicked off
• Sleeveless design to reduce overheating and maintain warmth
• Warmth level: 1.5 tog, suitable for room temps around 69–73°F (21–23°C)

Practical, Everyday Use

Two sleep sacks arrive in a convenient two-pack, and each is machine washable for simple care. Choose from four sizes to fit your growing toddler: S (0–6 months), M (6–12 months), L (12–18 months), and XL (18–24 months). Measure your baby’s height and weight and reference the size chart to pick the best fit.

• Two-pack for quick replacements and spare sleepwear
• Machine washable and dryer-friendly on low heat
• Sizes S, M, L, XL with a reliable size chart

With these thoughtful features, the Unnivoll sleep sack aims to support comfortable nights for your baby and easier routines for you—emphasizing warmth, safety, and practical care rather than guarantees.
