Would be perfect if it had a waist strap
"This bad is awesome . . . except it has no waist strap. When expanded, it holds about 30L, perfect for a week-long (or longer) trip for smart packers. But when fully packed, it needs a waist strap for support. I was excited when I could fit enough for a 9-day international trip in it, but returned it because I didn't want to be hauling it through airports, trains, etc. with all the weight on my shoulders. A strange omission, I think."
