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.

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!
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!

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!

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!!

Super comfortable and very good quality
My daughter loves the comfort of this sleepsack and has actually asked to wear it. With her other ones she fighta to put them on but this one is just the right weight for warm weather or heat on with a warm blankie. It is very soft and durable and easy to wash. Highly recommend. I wish Woolino would make a 1.0 tog version of this.

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!!!

This sleep sack is so lovely. I wish it came in other colors and patterns. Worth every penny. The sleep sack is made with a thick weight cotton and is very high quality and soft. The zipper is really great as you don’t have to mess around with lining it up like some of the other sleep sacks as this can be hard to do with a wiggly toddler. I bought the largest size and it fits my 29 month old toddler really well with plenty of room to grow (plenty!!) compared to other brands. I like that even tho it’s a longer sleep sack that it still fits nicely at her chest area and isn’t swimming on her like the others I’ve had. Thank you!

I loved this sleep sack. It's soft, the perfect weight, and the quality seems fantastic even though it's a lower cost option than the Woolino. Unfortunately, a few weeks after buying it, my baby decided he doesn't want to wear sleep sacks anymore because he demands that his legs be free. He likes to sleep with his legs dangling through the crib slats because he missed the part in Baby School where they explained that's a weird thing to do. So I mostly just look at it now. I wish they sold it in grown woman sizes. On the bright side, it's still my baby's favourite sleep sack to wave around, suck on and play peekaboo with.

It's a great sleep sack. I wish the zipper went from the top to the bottom instead, because sometimes my kid can undo it. Overall, it's the perfect weight though. It washes well.

I really liked how soft the material is. It fits well in the torso, not too baggy, and is nice and long to give lots of room for their legs and feet! It is a little thinner than o had hoped so I tend to use it under a fleece sleep sack as well since it’s colder at night in our house.

I really like the sleepsacks; they are long and stretchy, my kids have enough movement in them to not be snug. The material is nice and soft. I think it could be used all year. Will be getting another color. Highly recommend.
