Storage: 2 Zipper I.D/Key pockets
I recently purchased this belt along with (2) of the flasks and holders. I committed the ultimate error and wore the belt for a marathon 2 days later. I was very disappointed with the belt and mostly the flask accessories.
The belt never got tight enough for me, and when it was it continuously spun around my waste that I was continuously adjusting and fixing it the entire race.
The Fuel Flasks and Holders are a true waste of money in my opinion. The holder is a mesh material that did very little to hold and support the flask during the run. The flask fell out of the holder once before the race and two other times during the race that I had to completely stop, avoid being run over by people behind me and then pick it up and wipe off the container. I thought this would be a fantastic addition to my race attire, providing a quick means of accessing fuel during a run and additionally it would eliminate having to through gel wrappers on the road side, but unfortunately the design in my opinion needs more refining before I will use it again.
In my opinion I would save your money and wait for future design releases with some very crucial improvements.
