Took the vest out for a maiden 20 mile run this weekend. Had to bring jacket and gloves as well as food and full bladder. Everything fit in its place. Bite valve will take some getting used to, and you can switch it out, but otherwise everything was intuitive. Pull gel from a pocket, slide wrapper into trash stash. Jostling pocket, pull the cord. Right amount of space for 50 miles unsupported with handheld or other bottle in a pocket. Probably too small if you need to stash thicker clothes. Small/medium size fit my 5' 8" 135 lb torso. After going through a few other vests and belts, I think I found my match.
