Query: nice sleeping bag!

We received the sleeping bags fast and on time. We camped with them and the kids love them. My kids are 2 and 3 and did not have a problem with using the sleeping bags. My two year old was unable to unzip the bags fine and they did not get stuck. We camped in rainy and colder conditions, but they stayed warm and toasty in the bags. The color is nice for boys and girls, especially since they are darker and do not get dirty as soon as a light colored ones. I have washed one of them on the camping trip and it held up really nice. Both of them were washed when we came home and they held up nicely. They are warm enough for cold weather and easily cared for. They fit in the stuff sack when neatly rolled up, as you would with any sleeping bag.
