Awesome sleepsacks!!!
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.
Great high quality sleep sack for growing toddlers!
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 donât 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 itâs a longer sleep sack that it still fits nicely at her chest area and isnât swimming on her like the others Iâve had. Thank you!
Mom’s favourite sleep sack
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.
Perfect Fit, Thinner than Expected
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 itâs colder at night in our house.
Lightweight and comfortable
Perfect for summer weather! My tall two year old has lots of room to grow
Best sleep sack for summers
This is my 2nd sleep sack from ecoline as in canada amazon was better option to purchase because i need it for next day and delivery was fast and especially this sleep sack is the only one my toddler loves to sleep in either at home or her daycare
High quality & thoughtful
The zipper from bottom-up is key for quick bedtimes. Material and zipper seem quality and breathable.
Not lined
This is light – I was surprised it was not lined as there are exposed edges inside that look a little uncomfortable. It has been hard to find lighter sleep sacks in this size though so I will keep it. The one I received was also NOT silver as pictured, it was tan. I am a little unimpressed overall but it is fit for purpose.
This is a wonderfully soft and well made sleep sack. Itâs 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). Itâs 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 woolinoâs 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.
It’s perfect for summer daysâlightweight but very snuggly! The fabric is incredibly soft, and my 2.5-year-old loves it! It doesn’t shrink in the dryer.
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.
We love this sleeper! So soft and great quality. Love the cotton material and the two way zipper.My only âcomplaintâ about this sleeper is that the head hole is massive. No way he would have been able to wear this from birth. He is almost 5 months and it is just recently fitting well enough to not slip over his face. And my kid doesnât have a tiny head (75th percentile). Maybe it was just a fluke with ours. But now that it fits him it is wonderful! Will definitely be able to use past 6 months which is great since we just started using it.
This is a very soft and cozy sleep sack, BUT my toddlers ask to wear it because they know itâs easy to remove. As soon as I leave the room, they both just pull it off slipping their shoulders easily through the neck opening. Itâs quite large on them, so itâs very easy to get out.
