I'm looking for a tankbag larger than the one I have. Its okay for daytrips but won't hold all the things I take on multi-day trips plus the two cameras that I carry. I saw an ad for this one at Walmart and really liked the price but it doesn't say how large it is in liters. I figure I need at least 18L and prefer 20L. Anyone familiar with this one or do you have any suggestions?
