Got lot's of Kriega products for my motorcycle which has stood the test of time in all kinds of weather.Bought this Backpack for my Son as a schoolbag. He loves it's robustness and design.Well, I know it's quality and he thinks its COOL!!!!Great day ride rucksack, i'd heard about the straps being comfy, it's amazing, they really are. Handy pockets around the item, and feels solidly made. I'm not sure if it's waterproof or not, but i rode in a shower with it and nothing was wet inside.Worth the spend.if you are looking for an absolutely bullet proof rucksack for the bike or just for general use you won’t be disappointed with the Kriega R20.It really is a quality item that I think is going to be my daily bag of choice. Once it’s set you just chuck it over the shoulder and either secure the chest strap or not if you are just about town. Easily packs some clothes, iPad, phone, glasses, wallet etc and when the chest is clipped it doesn’t move about the back and leaves the arms surprisingly unrestricted. Brilliant!This bag is great. I ride a sports bike and it has a deceptively large capacity. I do not notice it whilst I’m on the bike. It also doesn’t interfere when doing over the shoulder checks and easy to put on and take off whilst wearing leathers.
