Unnivoll Fleece Baby Sleep Sack 6-12 Months | 2.0 Tog Wearable Blanket, Yellow & White Flower

Overview

Meet the Unnivoll Fleece Baby Sleep Sack for 6-12 months—a cozy wearable blanket designed to bring warmth and security to cooler nights. Crafted from high-quality 100% microfiber polyester, this sleep sack offers a soft, skin-friendly touch that keeps your baby snug while they sleep. It’s CPSC-certified, helping create a secure sleeping environment with a calm, reassuring feel for you and your little one.

The sleep sack pairs a plush outer fleece with a longer, softer interior fleece to lock in warmth without adding bulk. The result is a tactile experience babies respond to—a gentle texture against their skin and a comforting cocoon that moves with them as they sleep.

Warmth and comfort you can feel

Designed for indoor temperatures around 64-70°F (18-21°C), the 2.0 tog rating provides balanced warmth for fall and winter nights. The combination of a cozy outer layer and a soft interior helps your baby stay warm without overheating, offering a reassuring layer during bedtime routines.

• Soft surface fleece is gentle on delicate baby skin and reduces irritation.
• Longer interior fleece secures warmth while staying breathable for comfort.

Smart design for easier nights

The sleep sack features a premium smooth two-way zipper, enabling quick, discreet diaper changes during nighttime wake-ups. A zipper guard at the top protects your baby’s chin from scratches, keeping comfort and safety a priority.

• Two-way zipper allows changes from bottom to top or top to bottom with minimal disruption.
• Top zipper guard minimizes chin and face irritation.

Roomy, safe, and growth-friendly

The design provides ample room for kicking and movement, while a sleeveless silhouette helps prevent overheating and allows free arm motion for self-soothing and play. This balance aims to help your baby stay warm yet comfortable through sleep transitions.

• Roomy fit supports natural hip movement and growth.
• Sleeveless design reduces heat buildup while retaining warmth around the torso.

Practical and easy to care for

Included as a 2-pack, these sleep sacks are machine washable and can be dried at low temperatures for quick reuse between naps and nights. Four size options—S (0-6 months), M (6-12 months), L (12-18 months), XL (18-24 months)—help you choose a fit that matches your baby’s height and weight based on the size chart.

• Two-pack convenience supports everyday use, travel, or daycare transitions.
• Low-temperature washing and drying simplify busy parenting routines.

Real-life use ideas

Imagine a calm bedtime ritual where fleece warmth wraps your baby in a cozy cocoon, promoting a peaceful night and easier sleep transitions. When you move between rooms or travel, this wearable blanket remains a familiar, comforting layer that travels with your child. While not a medical claim, many parents find that a snug, well-fitting sleep sack contributes to a more predictable bedtime routine.

With four sizes available and a clear size guide, you can pick a version that fits your baby’s current height and weight, with room to grow. This product emphasizes comfort and practicality to support your evenings and mornings, rather than promising guaranteed outcomes.
