I was trying not to use a backpack. I realized that I was trying to minimize too much. I just got a tactical pack and it is great. So much easier to carry everything and should be easy to carry a couple liters now. Also a backpack with my yucca tube quiver strapped to the side works great. Almost set for hunting this year. Now I need to get some money to buy a decent pair of binoculars. My small monocular has served me long enough.
