Unnivoll Fleece Baby Sleep Sack 6-12 Months - 2.0 Tog, Long Sleeve Wearable Blanket with 2-Way Zipper

Cozy, safe warmth for growing babies

The Unnivoll fleece sleep sack is a snug, wearable blanket designed for little ones aged 6 to 12 months. Made from soft 100% microfiber polyester, it offers a gentle touch against sensitive skin while delivering durable, everyday comfort. Certified by the Consumer Product Safety Commission, this sleep sack supports a secure sleeping environment without restricting movement.

Ideal for indoor temperatures around 64–70°F (18–21°C), the 2.0 tog weight blends warmth with breathability. The outer fleece has a fine, rich surface feel, while the interior fleece delivers a cushioned, cozy layer that helps your baby feel enveloped and secure through nap times and overnight rests.

Designed with real-life routines in mind, the sleep sack features a premium two-way zipper and a protective top guard. This setup makes nighttime diaper changes quicker and smoother, helping minimize wake-ups while keeping delicate skin shielded from snagging or pinching.

Smart design for movement and warmth

• Roomy enough to allow kicking and free arm movement, yet snug enough to stay put through the night.
• Long sleeves provide added coverage for chilly nights, without overheating the toddler.

Two identical sleep sacks come in each package, offering convenience for busy families. The design supports multiple growth stages with four size options—S, M, L, and XL—so you can pick a near-perfect fit as your baby grows. When it’s time for wardrobe refreshes, these sacks are easy to care for: machine washable and dryer-friendly on low heat.

What makes it practical and versatile

• Two-pack value for streamlined laundry and rotation during busy weeks.
• Simple sizing guidance helps you choose by height and weight for a secure fit.

With a playful dinosaur pattern in a modern medium grey and white palette, the Unnivoll sleep sack blends nicely with nursery décor while offering practical warmth and comfort. It’s a thoughtful option for parents seeking a reliable wearable blanket that aligns with everyday routines and sensory needs—without promising guarantees, but with meaningful possibilities for peaceful nights.
