A simple drawcord converts the Mammut Magic rope bag from a freestanding rope bucket to a shoulder bag or a mat for sitting on. It opens flat for use as a mat and offers easy transport and storage.
Mammut's Magic Rope Bag transports your rope and all your other climbing essentials to the crag and then once you're there, it transforms into a comfortable mat to sit on. As a free-standing rope bag, the Magic protects your rope from dirt and dust while you climb, but when it comes time for a break, pull the drawstring and the bag flattens into a mat for some relaxing. The bag has internal rack-organizing straps and a secure zipper and drawstring closure so that you're not losing carabiners on your hike back to the car.
