I went the Slimline backpack way for a while and then I screwed up and shot a Tom and had to haul him out...I really missed the game bag on the back of my vest
Switched to a pack this year. I like to carry layers, snacks, water, etc. and if I’m using a gun I can strap one of those bag-style chairs with the short legs to it. That chair alone has been a game changer. Broke my tailbone years ago and it still gives me fits. The chair has all but solved that problem.
I carry a vest, due to my preference to carry 4 or 5 different frictions call (2 box calls and 2 crystal calls), along with other small items. I do not like the vest I have, but it was free and have been getting as much use as I can out of it. If you carry a lot of small items a vest is the way to go to organize it all and to have quick access.
Hmm now you’ve got me thinking...I don’t have many calls, I could probably get away with my fanny pack and bino harness, maybe with a little draw string pouch for a slate call. Would just have to figure out a good way of adding a seat.
I keep a Wet Box and some mouth calls in one belt pocket and a slate with a couple strikers in the other. No dekes for me on a run and gun, and snacks, water and a rain jacket in the big pouch with a small tripod stool strapped underneath. Liking it so far.
