Yoofoss Baby Sleep Sack 12-18 Months TOG 1.0 2 Pack 100% Organic Cotton

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.

Love these sleep sacks, they are true to size and a nice material. Love the double zipp for easy diaper changes. They are adorable and quite soft. This is a one tog, and a little heavier than the normal .5 tog, to help keep baby warm. These are a great value and I would definitely buy them again.

I like these alot. Baby #2 and this is the first time we have used sleep sacks, but these have been a life savor. Our room stays pretty cold at night and other than snuggling with me it seems like he cant stay comfortable enough at night & a blanket is a no go because he kicks his feet and the blanket would cover his face. These are light weight but thick enough to keep him warm at night. They seem made fairly well, with good material. Fits pretty good, with room to grow, so I feel like its true to size (my boy is 5 months old in 6 months or 6 to 9 months clothes since he was 4.5 months old 😅) easy to use for diaper changes at night because of the two way zipper, which I LOVE.

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!

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 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 really enjoyed these, they worked very well for us! Fit my daughter wonderfully, and are soft and warm. I wish there were more pattern choices but meh, not a big deal.

Mom of 3 here. I bought these to be a back up and they have turned into my everyday sleep sack. The thickness and softness are everything I needed and my baby can easily roll around to get comfortable. I live in the southeast with a very moderate climate, and the 1.0 TOG looks like it will be perfect for the majority of the year.
