I’m so glad I found these Yoofoss sleep sacks! I’ve tried several brands, and this 2-pack is hands down the best value for the quality. The fabric is super soft and breathable—perfect for our 72°F nursery. The 1.0 TOG weight keeps my toddler cozy without overheating, and we’ve had no sweaty wake-ups since switching. The two-way zipper is a lifesaver for nighttime diaper changes (no more full undressing!), and the zipper guard at the top is a thoughtful touch to protect their chin. After multiple washes, the sacks still look and feel great—minimal shrinkage, seams holding strong, and no fading. Sizing is true to size, though if your little one is on the taller side, you might outgrow the smaller size range sooner. I love the roomy fit for kicking legs and healthy hip development. And the designs are super cute and gender-neutral, which is great for hand-me-downs. Highly recommend if you're looking for a safe, comfortable, and well-made sleep sack. It’s really helped our toddler sleep longer through the night—and made my life easier, too!

Baby loves this sleep sack and is sleeping so well in it. It's super soft and cozy and is warm enough for the cold winter nights I love that I can take the arms on/off to adjust depending on the temperature

Warm, good quality, reasonably priced and washes well! Zipper is good quality as well! Very comfortable and I can trust my baby is warm and cozy through the night with this on. Perfect for the chilly nights. My husband and I like to leave the house colder at night, and now I don’t have to worry about the baby while we are comfortable
