Soft, Lightweight, and Perfect for Peaceful Sleep
I’m really impressed with the Yoofoss Baby Sleep Sack 3-pack. The 0.5 tog is perfect for warmer weather or for layering over pajamas without overheating. The organic cotton is incredibly soft and gentle on baby’s skin, and the lightweight feel keeps my little one comfortable throughout the night. The 2-way zipper is a lifesaver during late-night diaper changes—super quick, quiet, and convenient. The sizing (0–6 months) fits well with room to grow, and the overall quality feels excellent for everyday use. These sleep sacks wash well, stay soft, and hold their shape. If you’re looking for breathable, easy-to-use wearable blankets that help baby sleep comfortably and safely, this set is a great choice.

Comfortable and Practical Choice
The soft, breathable fabric keeps my little one at a comfortable temperature overnight, and the appropriate TOG rating works well for cooler rooms without overheating. The zipper design makes midnight diaper changes quick and easy, and it washes nicely without losing shape. Compared to pricier brands, it offers similar quality and safety features at a more affordable price, though the zipper guard could be a bit softer against sensitive skin. Overall, a solid, everyday sleep sack that gives parents peace of mind.

Would buy again
Good quality, thick material - definitely feels like a blanket that has a little bit of a weight to it. My LO sleeps like a rock whenever we use this sleep sack. Only con is that I’m not sure if it will last until 6 months because my LO is on the bigger side. Would buy again.

Best One to Buy
Absolutely love this sleep sack! Super soft and thick for the winter days. Two way zipper is always a game changer. Baby girl loves it with plenty of room to move her legs. It keeps her warm and keeps me at ease with no worries about safety. Washes great with no tears or shrinking occurring. She is a big 4 month old so I got her the 12-18 month size and it fits great!

Great sleep sacks. Highly recommend
Love these for my daughter. They are light and airy but still will keep her warm enough at night. They are stretchy and she has a lot of room in them. I bought the 6-12 month size and they are true to size. They don’t get tangled up when she is rolling around and they seem to be good quality material. Easy to put and take off. They have a double zipper so it makes night time diaper changes easy.

Soft, Warm, and Great Quality (Just Size Up!)
Overall, this is a really good quality sleep sack. The fabric feels soft and comfortable, and it keeps my baby nice and warm throughout the night without overheating. It seems well made and holds up well with regular use. The print is super cute! The only downside is that it did shrink a bit after washing, so I’d recommend sizing up if you’re on the fence. Aside from that, I’m very happy with this purchase and would still recommend it.

Warm and cozy
Not only is this soft but it is plenty warm for when our temps drop at night. Our heater only does so well and sometimes it still gets down to the 60s in our house. This sleep sack stays on well, gives my son plenty of leg room and keeps him warm. Plus, the double zipper makes it to where we don't need to completely take off the sleep sack for a diaper change which is awesome since it keeps the warmth inside.

I did not like this sleep bag. It was not soft. It was also MUCH thinner than other 2.5 tog sleep bags that I have since bought. This was more like 1.0 tog. If you’re looking for 2.5 tog, this one won’t be warm enough.
