Yoofoss Baby Sleep Sack 6-12 Months TOG 1.0 Baby Wearable Blanket, 2 Pack 100% Organic Cotton Infant Toddler Sleeping Sack 2-Way Zipper Lightweight Sleep Sack

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.

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!

Cute light weight sleep sack. 100% cotton which makes it breathable and perfect for hot climates. It fits my 6 month old well, and will fit last her a few more months owing to it large size. Functions perfectly with the dual zippers,the fabric has a little bit of stretch (cotton), and my kiddo seems comfortable in it.Ps the animal design on it is so cute and silly. Love it.

Why did you pick this product vs others?:We keep our house between 68-70 and with a onesie and footed/mittened pajamas, he stays warm with this sleep sack. He outgrew the swaddle wrap we had, and this has been so much more comfortable for him! I like the material and the bottom zipper. The top of the sack with the zipper seems to ride up a bit, but the zipper cover has kept him protected. Washed and dried with other clothes and it has faired well.

I ordered a size small for my 3.5 month baby.Material: We are transitioning him out of the Halo sleepsack swaddle. This material seems a little bit thicker than the Halo swaddles but my baby didn’t show any signs of being too warm while sleeping in this.Sizing: I saw some reviews that said to size up since these tend to shrink in the dryer. It did shrink a little bit. I’ve posted a picture of the two sleep sacks, where I’ve washed and dried the white one but not the green one. It did shrink a little bit, but still fits fine. I do think in general this might be too short by the time my baby is 6 months old, but it will hopefully last a couple of months. Right now it fits well around his neck / chest area with a little room for him to grow.Quality: I’ve only used these sleep sacks for about a week now, but the quality seems great. It’s breathable, slightly stretchy, and seems to be comfortable for my baby. The two zippers make diaper changes easy- much easier than the Velcro we were dealing with while using the Halo sleepsack swaddle.

I love the material and the thickness. They are so nice and comfy and keep my baby snuggy warm.The only problem I have found is after washing them they shrunk. My baby is typically on the smaller side (7 months old) so I thought the sleep sacks would be used for a while, bought size 6-12 months. They fit him so well right now but I know he'll outgrow them sooner than 12 months old. I hate that they shrunk, but are otherwise good.

This sleep sack is great! It is soft and durable. It has a quilted feel which provides warmth and comfort.

I was worried about using blankets to keep my baby warm at night. She’s 7 weeks old. I did some research on baby sacks and found these and a few others that were more expensive. I decided to give these a try. They’re 1TOG and in my opinion it’s perfect for the spring and autumn. My baby loves it - it keeps her warm and the fabric is soft. The quality is also better than expected! My only complain is that sometimes the sack gets too close to her neck and it makes me nervous but most of the times it’s because my baby wiggles and the sack ends up closer to her neck.Summarizing, if you want good quality sacks that are affordable, these are my recommendation.
