Perfect for my Baby Space Heater!
This sleep sack has been absolutely a godsend for my son! He heats up like a battery pack and was getting heat rash just from sleeping in a cotton sleeper in the winter with the heat set to 70°. His pediatrician recommended that we keep the room as cool as possible, but I still wanted him to have some sort of “blanket” just in case he did get cold! This was the perfect solution to keep him comfortable! The material is light enough that he can be kept warm, but with the Ideal Temp fabric, if he gets too warm he won’t overheat. I have never picked him up and felt like he was too hot or too cold. He The quality is fantastic, I haven’t noticed any issues at all and we’ve been using it nightly for the last 2-3 months. It has fit him incredibly, however he’s a longer baby so we are already having to size up at 4 months old, but there’s no question that we’re sticking with this for the next size! Love that it unzips from the bottom, so no need to get him fully undressed for diaper changes!

Obsessed!
Obsessed with this sleep sack, I love the fabric, it’s light weight and perfect for summer nights. Love the color wave, texture, and zipper quality. It’s the perfect size and length and very durable. I’ve washed this more times than I can count and the quality has remained the same. 10/10 would recommend!

Soft and cozy
We purchased this for our son and he seems to be comfortable in it. He never wakes up cold or too hot so it must keep him at a good temperature. It’s easy to zip him up and it has a two way zipper if you need that for diaper changes. We love the Halo brand products.

Go-to for warmer temps
Perfect for warmer nights. Feels thin to touch but is just enough of a cover to keep them warm without overheating. Halo is my all-time favorite swaddle. Cannot recommend enough! Amazing quality!

Improved independent sleep
Love these so much. My little one hates being swaddled but these sleep sacks have helped so much with him sleeping better on his own. It feels light like a muslin swaddle but provides enough warmth for our room that is around 73 - 75 degrees.

Nice sleep sack but seemed thin for 1.0tog
A wonderful sleep sack for my child! The material does seem a bit more lightweight than other 1.0 tog sleep sacks we've used. It is a thin material which was nice during the warmer months but I worry it would not have been warm enough in the winter (we had to size up before the cold weather). The material and zipper held up well throughout many washings and the color stayed vibrant. Easy to get my son in and out and didn't have any issues with ripping or tearing. In fact, this is the one thing my son has attached to and it is now his lovey!

Lightweight and keeps baby warm during the summer. Not suitable for the colder months. Baby girl is comfortable and can roll over with no problem. Looks very cute and baby girl sleeps good.

We got this for my baby when she was like 10 months old, she's over 2 years and still sleeps with it even though it's not quite long enough, just half zips it, it's like a comfort thing for her now. Still in good shape, just has a small hole at the bottom of the zipper. 10/10, would recommend.
