This rope bag is designed exactly for what the name says "on the go." It has two main compartments with three dividers and a small back compartment with a separate storage area. It has a zippered pocket in front and a medium pocket with a hook and loop closure. It has a water bottle pocket on the front and a cell phone pocket on the backpack straps. This is a super handy design because you can put it on like a backpack when you ride from the trailer to the pen and have your phone in front close to you if your horse boogers!!
