Buttery Soft and Cozy – Crafted with 95% rayon made from bamboo and 5% spandex, our Baby Sleep Sack is softer than cotton or wool, offering unmatched comfort for your little one. The breathable fabric naturally regulates body temperature, wicks away moisture, and helps prevent overheating. This means your baby stays cozy, dry, and comfortable all night long—ensuring a peaceful sleep.
Safety First – Your baby’s safety is our top priority. The Yoofoss Baby Sleep Sack is CCPSA-certified, meeting the highest safety standards. Our carefully designed neckline and sleeveless cuffs ensure a secure, snug fit, preventing your baby from slipping inside the sack. Plus, the spacious leg area supports healthy hip development, giving your baby room to move naturally.
Convenient 2-way Zipper & Fully Openable Bottom – Changing diapers just got easier! Our Wearable Blanket Baby features a smooth 2-way zipper and a fully openable bottom, allowing quick and hassle-free diaper changes. The zipper guard protects your baby’s delicate skin, keeping them safe from any irritation or scratching.
Optimal Warmth with 1.0 Tog & Quilted Design – With a 1.0 TOG rating and a soft inner quilted design, this Toddler Sleep Sack provides just the right amount of warmth for year-round comfort. Perfect for sleep at home, in air-conditioned rooms, or during travel, this sack ensures your baby remains cozy whether it’s a nap or a long sleep.
Long-Lasting – Designed for durability, this Baby Sleep Sack 6-12 Months can withstand millions of washes without losing its softness. The shrinkage rate is less than 2%, even after machine washing and drying on low heat. Available in 4 sizes to perfectly fit your growing baby—S (0-6 Months/10-18lb), M (6-12 Months/16-24lb), L (12-18 Months/22-28lb), XL (18-24 Months/26-34lb). Be sure to check our size chart for the best fit.

So soft
I really like this sleep sack, itâs nice and warm for baby and really soft. Feels like a comforter.
Great quality, very warm
Iâve had it for a year so far, great quality washes well. Shrinks very slightly in the wash but stretches back out. Stays very soft, fluffy and warm. Initially the arms were bigger than I expected but not too much of an issue since baby has grown. Flexibility of arms and zipper is great. Zipper quality also great, still working great after a year.
Warm snuggly sleepsack
I was looking for a soft warm sleepsack for a camp out. I think this will be perfect.
