I leave the house every morning with 1-bib, 1-jersey, and 1-MTB short stuffed into the main compartment. I stick my post ride crocs in the shoe compartment and head off to work. After work at the trailhead I change out of my work store and stuff it all back into the bag. This exchange keeps everything in on place and organized and I LOVE IT! I also regularly keep a hat and sweatshirt in the helmet compartment as most of my gear is stored in the car. I even use the top compartment to store chapstick and bubble gum, or snacks on occasion.
This thing has interior pockets for gadgets and even a bottle opener ha!! Awesome bag! Truly awesome.
I have it packed for mt biking and cyclocross, and I just adjust what's in it as needed. I love the shoe compartment. Lots of pockets and dividers make it easy to separate clothing, tools, and snacks, and keep everything easy to find.
