Yoofoss Baby Sleep Sack 6-12 Months – 1.5 Tog Fleece Wearable Blanket with 2-Way Zipper

Safe, Soft Sleep for Growing Babies

The Yoofoss Baby Sleep Sack for ages 6 to 12 months wraps your little one in a gentle, breathable fleece layer. Crafted from 100% polyester, it is designed to feel smooth against delicate skin while supporting a warm, secure night’s routine. Certified to meet CPSC safety standards, this sleep sack emphasizes protection and coziness without restricting movement.

Inside, an 8 mm plush panel adds a comforting touch that can help soothe your baby as they settle. The design leaves ample room for kicking and natural hip flexion, which can be important as your baby grows and explores new sleep positions. This wearable blanket blends warmth with freedom, making bedtime feel like a nurturing, predictable moment in your daily routine.

Two thoughtful features elevate everyday use: a hidden 2-way zipper with skin-friendly protection and double zippers for easy dressing and nighttime changes. The zippers glide smoothly and are designed to prevent snags, helping you handle diaper changes or quick on/off without waking baby.

Versatile warmth for varying seasons

With a 1.5 tog rating, this sleep sack is designed for moderate temperatures around 69 to 73 F. The long sleeve design keeps little arms cozy while still allowing full range of motion, making it suitable for autumn, early winter, spring, and even cooled rooms in warm-weather homes when air conditioning is on.

Available in four sizes, from S to XL, the sleep sack grows with your baby. The packaging includes a 2-pack option for added value and convenience, so you can rotate between outfits or keep a spare ready for busy nights. It is machine washable, ensuring simple care after everyday wear and inevitable messes.

What to expect at bedtime

Parents may notice a smoother routine as the wearable blanket provides a consistent layer of warmth without the fuss of loose blankets. The soft fleece and secure zipper design can help reduce worry about coverage during sleep, while the sleeves provide warmth without overheating the arms. This makes the sleep sack a practical choice for daily use and travel alike.
