Yoofoss Baby Sleep Sack 12-18 Months TOG 1.0 Baby Wearable Blanket, 2 Pack 100% Organic Cotton Infant Toddler Sleeping Sack 2-Way Zipper Lightweight Sleep Sack

High quality, very warm and soft material. Double Zipper comes in handy for late night diaper changes.

Nice thickness from the double layer of fabric that feels nice. Two way zipper is super nice. We’ve had it about three months and so far there are no signs of wear from the washer/ dryer.

Been eyeing this sleep sack for awhile because I did not want to spend 50$ on the leading competitor, Halo. Wanted something that was heavier for the winter but also something that gave him legs room since baby likes to sleep with his legs always to his side. Baby slept great and it helped establish a good bed time routine. The quality is so nice and soft and i loveeee the quilted design. Has a zipper on both top and bottom for easy diaper changed. Easy to wash in the machine. Depending on the weather it definitely gets too hot (2.5 TOG) will definitely buy from this brand again and will get the lower TOG

I bought a few of these in different colors. The value for your money is great and zipper functionality is perfect. I like that. It has a fabric tab to cover the top of the zipper to avoid rubbing on my babys chin. The colors were as pictures and the fabric weight it light enough to keep warmth in without sweating your baby out. The fit is as expected and the fabric does stretch when they kick but not too much which is nice.

I order this sleep sack looking for dupes of the Halo Sleep Sack. The materiel is soft and lightweight while also providing great warmth, at night the house is cold and baby’s temp is maintained well. I’ve washed the sleep sacks multiple times and there is no shrinkage and still maintains its stretchiness and color. It works very well and I have no issues with the zippers. The size is as the chart follows although if your baby is on the bigger/longer side you may want to size up for more leg room. Only small complaint I have of the cover for the top zipper is a hit or miss and will not always cover the zipper all the way.

We’ve used these every night for the past few months and they have held up great! They are comfortable for our twins and have fit them for the last few months without having to buy the next size up. They’re soft and well made and perfect for the temperature we keep our house at (about 70 degrees). We will definitely be buying the next size up soon!

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!

As a parent of a 3-month-old (and 3 older children), I’ve tried several sleep sacks, and this 2-pack has quickly become a favorite. I’m writing this review after several days of nightly use and multiple washes, and I feel confident recommending it to other caregivers. ✅ Comfort & Material: The fabric is exceptionally soft and breathable—perfect for my baby's sensitive skin. The 1.0 TOG weight is ideal for a moderate room temperature (we keep the bedroom around 70-72°F), offering just the right amount of warmth without overheating. My baby seems noticeably more settled when we use these compared to heavier or stiffer options. ✅ Design Details: The two-way zipper is a game-changer during late-night diaper changes—quiet and smooth, and there’s a zipper guard up top so it doesn’t rub against her chin. The armholes and neckline are snug without being restrictive, which gives me peace of mind in terms of safety. ✅ Durability: I’ve washed both sleep sacks several times now, and there’s been no fading, pilling, or shrinking. They come out of the wash just as soft as when they were new. I also appreciate that the green color is a calm, gender-neutral tone that goes with anything. ⚠️ Minor Note: Sizing runs a little on the smaller side. At 3 months (around 13 lbs), my baby fits perfectly in the 0–6 month size now, but I anticipate needing to size up soon. It would be helpful if the listing included a more detailed sizing chart based on weight and length. 🎯 Final Thoughts: This sleep sack set checks all the boxes: soft, breathable, well-designed, easy to care for, and safe. If you’re looking for a lightweight sleep sack for spring, summer, or a climate-controlled home, I’d absolutely recommend this one. I’ve already bookmarked the larger size for later.
