I used this bag for the first time during a 100K looped course. I did not have a drop bag, but used this at the spot where my crew was the whole race. It was the perfect bag to keep all of my gear organized. I knew exactly where everything was located, saving me time (and mental energy!) when seeing my crew. I love all of the pockets and adjustability of compartments (removing certain pouches etc.). The bag is durable and will be a great drop bag for future races!
