This is nice and snuggly warm. The top unzips completely from the bottom, which is convenient for days with wide temperature variation. Great for stroller and car seat, and easily installs/uninstalls in both. Washes well. Fits bigger babies.
It's kind of difficult to keep my lo's upper body covered because he pushes down the top of the cover.
for 0-3 mo or so I would recommend using the elastic-style cover that is basically a lid for the car seat with a hole for baby's face. The only reason I quit using that is because DS got too big for it.
I have the toddler size stroller one and absolutely love it! It keeps my son nice and warm and dry. We moved from southern California to Illinois and were not prepared for the cold! Luckily BS had these just in time and I was able to grab one at a great price. I don't have to worry about my son pulling off his blankets and not being warm enough. It attaches very easily to the stroller and is easy to remove. Great product.
