I have not used on yet. I thought about them. My question would be is the seal tight enough on the top and is there enough insulation there for you not to need a top blanket? I think that if I made a peapod I would think about putting the seal on the side. That way the user would have a full layer of insulation on top of them.
Another question would be is a peapod (along with any needed top insulation) lighter than an underquilt and top quilt, taking into account any needed suspension systems?
Is that too much to ask? Girls with frikkin' lasers on their heads?
