I use the Bear Boxer and I love the balance of weight AND shape. I say this, because the Bearrakade(sp) might be a few ounces lighter, but the size is not nearly as accomodating(unless there is a model I don't know about) as the solo Bear Boxer (which I have used for trips up to four days+)

PS check out EBAY -- that's where mine came from

The body betrays and the weather conspires, hopefully, not on the same day.
