Maybe a dumb question but I just bought a pannier backpack from two-wheel gear and I'm very pleased with it so far, but in some of their promo pictures they show that you can attach your helmet to it. I cannot for the life of me figure out how to do that – even if I loosen the strap on my helmet all the way it's too short to thread through the clips on the front of the pack. How do you do it?
