Excellent quality, so soft, lightweight and warm
This is a wonderfully soft and well made sleep sack. It’s relatively thin and lightweight while still feeling warm and snug. The fit and design of the sack keeps it in place and has prevented any bunching of fabric around the face (a problem I have had with other brands). It’s easy to get on and off with the single zipper.This item works great in a warm room given how light it is. We also find it perfect for a cool room when paired with warmer / heavier PJs - it adds an additional layer without seeming to overheat.The only thing to keep in mind is that this item does best when laundered alone in cold water, on a delicate cycle. I hang to dry or tumble dry low alone. This has avoided any pilling of the fabric and has allowed it to retain its silky softness. After several weeks of use it has retained color, shape, and the feel of the fabric out of the box.Overall I find this sleep sack only second to woolino’s merino wool 4 seasons sacks - which we also use and alternate with this cotton one. This is a great option at a much better price point. After using both this item and the merino wool sack, Woolino is likely the only brand I will use for sleep sacks in the future.

Great Sleep Sack!
Love this sleep sack! It does not show any signs of pilling, and I’ve owned it for a while now before providing my review. This sleep sack keeps my son warm and I bought one size up so that he could wear it longer. Zipper is perfectly functional and the fabric is very soft. Highly recommend this sleep sack and the Tog!

Perfect weight for summer nights in warm climates
We love the Baby Sleeping Bag, 4 Season Basic Merino Wool Wearable Blanket, 6-18m, Earth, but felt like it was a little too warm for hot summer nights in Georgia, even running the AC on full blast. So excited when we discovered these! They're super soft and a perfect weight - they feel substantial enough to be a nice blanket, but also lightweight enough that we know our son will be comfortable. Like the basic bag, they have the full zipper but no shoulder snaps (which is what we wanted.) Added bonus: unlike the wool bag, you can put these in the dryer! Half the price of the basic, but the quality is just as nice. And love the fact that it's 100% organic cotton.If you're new to Woolino, their bags are great. Our son is 16 months old now and 98th percentile height, and we struggled to find good sleep bags that were decent quality and large enough for his size. We prefer the ones that zip from the neck all the way down to his legs instead of shoulder snaps and a half zip. These are perfect. If we had found these sooner, we probably would have purchased these instead of the merino wool bags, but hopefully those will still fit next winter.Highly recommend!

Great sleep sack!
I love this sleep sack! The size is as advertised and the material is incredible. My only complaint is the stitching. The first one I received, the zipper had been incorrectly sewn on and couldn’t even zip open. The second one has a mistake around the zipper as well, but it’s usable so we decided to keep it. The integrity of the sleep sack overall is wonderful and I’m not concerned about it falling apart; it’s almost as if they sewed it too much!

Soft and rooy sleepsack for my 18 month old grandbaby
I love the size of the sleepsack. It is stretchy and leaves plenty of room for my grand baby to grow. The cotton material makes it so soft. Most sleep sacks I looked at did not go up to 36 months. My grandbaby is 18 months old and this is perfect. She can grow quite a bit and it will still fit. Yet it is not too big for now. I wish this company made one in a lighter weight and one in a heavier weight so that it could work regardless of the temperature of your house. It’s wonderful to know that she’s staying warm without kicking blankets off in the middle of the night. I do wish they also made one with loose fitting sleeves to keep her arms warmer. All the sacks I looked at with sleeves would be so heavy that the baby would overheat. I have purchased two so far and I am considering a third so that I have one to keep at my house when I babysit. Definitely a great sleep sack!!!

great for climbers
I wish I had know about this sooner. my 18 month old (size of a 3 year old) is a climber so we got rid of the crib a long time ago and just had her on a mattress with a high wall mounted gate surrounding her. she started to climb over that a few weeks ago. she is not mature enough to not be "caged in" so I asked around for advice and my mom saw a sleep sack as a recommendation. We could have kept her in the crib if we'd known about this sooner. she has plenty of room to move her legs around and can walk with it. But it does prevent her from being able to kick her leg over her head to pull herself over the gate. we've been putting it on her backwards to keep her from unzipping it. not only can I rest easier knowing I wont ne awaken by a loud thump, she's nice and cozy and sleeping better as well.

Love it
So glad that I bought this. My son is two and still sleeps in a sleep sack. It’s so hard to find them that are a good length at a reasonable price. This checks all the boxes! Good price, super long, good weight (not too heavy or light, and it’s nice and soft. We will definitely be buying more!!
