I've previously posted photos of my possibles bag on other threads. This bag is made of elk hide and I had a local leathersmith make it for me to my specs around 17 years ago. It is a rare hunt that you will find me without it. Presently, Stickshooter of Trad Gang fame is making me a knife to replace the Schrade model #152 shown in the sheath. The inside of the bag is divided into three seperate compatments and I leave one COMPLETE set of all of my bowhunting essentials in their respective compartments. in this manner, even in the dark, I can find what I need by FEEL.
I'm fortunate to be able to hunt where I live and much of my hunting is done in two-three hour intervals after work. By leaving my hunting essentials in my possibles bag (arm guard, knife, Accusharp, mini-mag flashlight, compass, hat, face mask, gloves, rope, leatherman, folding saw, extra bowstring, fleece neck gator, etc.) when I get home from work, I grab my bow and quiver, my possibles bag, throw on my scent free clothes that I leave outside in a extra-large tupperware container and I'm off to the deer woods.
When the weather turns cold, I'll roll up and extra wool sweater and cinch it to the bottom of the bag using rahwhide laces. I know it sounds corny, but you will find that you'll grow fond of your possibles bag to the same degree that you become found of a favorite bow. For preseason scouting and tracking a deer, a possibles bag is an absolutely invaluable tool. The key to using it successfully is to ALWAYS leave one complete set of essentials in it. In this manner, you can just grab it and go.
