The perfect sleep sack
This sleep sack was the perfect weight for summer and winter weather, super soft material and easy to wash.

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!

Great for summer
I used this sleepsack a lot in the summer. I don’t know if I believe the material is “temperature” controlled because the minute the summer nights got cooler I feel like she got too cold and I had to switch to the thicker sleep sack.

Thin, quality lacking
This sleep sack is very thin and low quality. There is already a hole after one wash. I’m not sure why this is priced is so high as it’s basically a very thin piece of cloth with arms cut out… I bought this because we had great experiences with other halo products, but not this one.

Baby’s naptime BFF
This sleep sack is very comfortable! The quality it’s great never had an issue with the zipper. My son is a very long and chunky baby so he’s only 2 months and 15 lbs about 2 ft in length in this photo but he’s in a size medium. It’s a great lightweight option for warmer temperatures.
