Whether we're riding up a transition enduro stage or chasing sunlight with our friends after work we use the Fox Transition Pack for all our stuff. This pack is big enough to fit our helmet, shoes, and a couple of water bottles as well as an entire change of clothes. We're using this bag to pack up for the workday knowing we're going to be hitting the trails right after. It's also a great weekend bag, and the huge volume of storage can make any weekend getaway feel like a breeze.
