This works for me, I used to lose more flies off my vest than to trees. I keep a cheap,small plastic fly box in the top pocket of my fishing SHIRT, along with an empty film canister for collecting mono tippet and spinning. I drilled a number of holes in each compartment of the box. When I'm done fishing and have placed my vest and gear in the back of the truck, I'll remember the used flies in my shirt pocket. I'll either open it on the dash on the drive back or lay the box over my heater. I have lost so many barbless flies with all the other gadgets, or lost the box in the deep inner recesses of my vest when placed in there.
