When I first got my strom it didn't have luggage, so I just used my cheapo 'coldwater canyon' backpack, and still use it now because I'm used to extra padding and material on my spine in addition to my olympia jacket. I find backpacks a great place to carry light clothes, for even more spine protection. The 'coldwater canyon' backpack is on it's last legs. Anyone use a high quality backpack that they ride with and like? What brand?
