This saddle bag will fit almost anything in that size range. It has awesome connecting devices which allow you to hang it off of almost anything! I use it for small tripods / monopods and as a thermos pouch. Nothing but Eberlestock quality, highly recommended...
No surprise when it all came together. I trusted that my Scout bino small and saddlebag would meet my requirements. It has. Added saddlebag to bino harness purchase anticipating using saddlebag as hydration bag. Purchased 2L bladder and it fits perfect and works well. Only have been on two hikes with it, but after minor tweets/ adjustments, works great. Versatile and light.
THIS WAS A CHRISTMAS GIFT. DON'T KNOW HOW THE RECIPIENT WOULD RATE.
Great piece of equipment to add to the m1 main frame
