Thule Rail Pro 12L Hydration Pack

We've all wondered if our loaded backpacks will keep us safer in a crash. The opinions are mixed, with the possible cushion from a hydration bladder being offset by any jabby pumps or stabby tools inside. With the Thule Rail Pro 12L Hydration Pack, you'll know for sure: this pack has integrated back protection, certified to protect you, should things go south. This is an endurotron's dream!
