Just picked one up and LOVE IT!!! For those that don't know, its the updated version of their failed palos fanny pack. Unlike its predecessor, this one will not loosen while riding, doesn't bounce much at capacity, and looks much better. 1.5L of water and just enough room for a spare tube, 8" mini pump, cell phone, snacks, multi tool, mini first aid kit, tire lever, Swiss army knife, tire plugs, extra hangers and links and car keys. All this stuff fits in there without it bursting at the seams. You barely even notice its there. This is my new go to for 1-2 hr rides. Just thought i'd share. This thing rocks!
