Unzips from the bottom for easy diaper changes. Generous sack design allows room for kicking, but cannot be kicked off so baby stays warm all night. Sleeveless design reduces the risk of overheating.
#1 Choice of hospitals. Used by hospitals nationwide for safe sleep education.
Recognized as “Hip Healthy” by the International Hip Dysplasia Institute.

I love this so much because my son does gymnastics in his sleep. He is 2, and this keeps him warm, especially on the colder nights, but also makes him feel cozy. I have used Halo sleeping wear since birth, and stand by there products.
I’ve used Halo sleeping sacks since my baby was born and they’ve been great! The micro-fleece type is convenient for a wide range of temperatures, I just change the type of PJ’s according to the season and the micro-fleece sack works for cold and hot season (of course not too hot or not too hot, our house has AC, so the temperature is always regulated). I’ve used them for many months, until I have to change it for another size, and they remain in perfect conditions. I’ve use the TOG 2.5 sleepsack and it’s been perfect too! Highly recommended. Zippers and fabrics have very good quality. Safe and comfy!
As I am living in a tropical country with hot weather.. The material is just nice for the weather..It is not too thick and neither too thin. My son sleeps well with this sleep bag! Recommended!
Overall good quality. This is nice to put on over light clothes when putting baby down for a nap.
My grandson is still sleeping with a sleep sac at 18 months for safety reasons. I have used the Halo baby boy sleep sac in the smaller size and loved it so I bought the larger size as he grew. It zips from the top down and has a tab to hide the zipper. It’s really soft and snuggly.
