Our Favorite Sleepsack
Fantastic quality. I couldn't find a sleepsack that would fit my 4 year old for the winter months until I came across ergoPouch. I love that it is machine washable and tumble dryable as well. I love that it also has foot covers that go over the feet. I just wish the price was lower.

So close..
I really wish this sleep onesie had the feet just as insulated as the legs/torso. The convertible sleep sack does, why not this one? My little one wakes up with cold feet because of it. Also it needs insulated arms. I end up still having to use a blanket with this (she wears jammies underneath--room ends up being 67 degrees) or an extra sweater underneath the onesie. I would gladly pay the extra money if the arms and feet were insulated. I've considered knitting flaps to cover the feet.. but at this price point that seems ridiculous.
