REI Volcano +15 Junior

I bought this as a birthday present for my 9 yr. old to take on what his 5-yr-old brother calls "Adventures." My son used it this weekend and he actually said it kept him too warm and that he loved it. The "problem" with the bag is that it fits him exactly w/no growing room, so the bag now belongs to my 5-yr -ld and I have to buy an adult bag for the 9-yr-old. But for the money this bag has already proven to be a big hit, let's see how it stands up to a small boy.
