I have repurchased both products in larger sizes as the sleep sack/swaddle is quite well made and comfortable, not just because it connects well with the Nanit monitor. It features dual zips so you can change a diaper without swaddling and I don’t recommend doing it any other way: The separate breathing band is convenient, but it can bunch up slightly or travel a bit. It’s important to place it snugly around the baby’s trunk with arms out but even with proper placement it did tend to move a bit on my wiggle worm. Also, a section within the Velcro on both items was a little stiff, but I think that portion is necessary for the Velcro to be as strong and as durable as it is. Some competing products see the Velcro begin to separate from the garment, but not here! That being said, they still worked well enough to continue using with lighter pajamas in warmer weather and to repurchase.

Material is comfortable around my baby's body. It is reliable for recording her heart rate. I have never had any false readings. The set up was super simple !

Love this! As a parent of a preemie baby, this helps me sleep better at night knowing she is okay. I have the sleep sacs as well as the belly bands and they all fit wonderfully. The accuracy is pretty spot on (I also use the owlet) and the nanit and owlet are always very near each other!
