Some instructions might have been nice initially! You have to zip the 2 bottom zippers all the way down and out to change it from bag to legs or vice versa. Easy once you figure it out! Easy diaper changes and when it's in a bag you can zip the bottom zippers down slightly to pass the carseat strap through it too! Not super bulky like a snowsuit and the chest zips will make it easy to make sure your little one doesn't get too warm. We will be using it in my stroller too! Cannot say enough good things about this bunting! Wish I had when my other two were this little and I wish it came in larger sizes!
