Not sure where to post this but..anyone had both the 15 and the 20 rucksacks? I’m trying to assess whether the extra 5 litres makes enough difference to upgrade from my 15. I’ve also got a 35 and that’s too much for what I need . Anyone??
Sorry if this is stating the obvious here but.... the 20 will be 33% bigger than your 15, this means you can carry 33% more stuff , or 44% less than you can carry in your 35
