I have thought on and off about using an upland vest like Mike recommends. My only gripe is that I have yet to find one that was decently made out of a quiet material.
I have just settled on a lighter, smaller back pack that is large enough to stick my heaviest jacket into the main pocket. Besides that, I usually only carry a knife, gloves, beanie, some paracord, a flashlight or headlamp, and some hand warmers.
My biggest negative to sticking stuff in your pockets has always been that I eventually leave something in my pockets. That is why I like the small, light pack. Everything is in one self-contained location. No matter what I am wearing (generally), I just grab the pack and "go" knowing that what I need is all there.
Remember (depending on where you live) to take your “one bag with everything “ out of the truck at the end of the day. I left a small fanny pack on the back seat of my truck a couple of years ago and while at work, at 0830 or so on a bright sunny Monday morning some scumbag popped my window with a glass breaker and grabbed the bag. I lost Leupy BX3 8x32’s, a Garmin Rino 120, a Nikon Acculon range finder, a stag Remington baby bullet knife and a TOPS knife as well as license, ammunition and probably a Clif bar....
My fault of course and I expect I’ll never see that stuff again but I’d sure like to know who did it. Local PD says the homeless around here will bust your window for 2 bucks in change in your center console. I guess I’m fortunate that it was a grab and go, I had 2 handguns in the truck at the time. Lesson learned.
