Army jacket and army pants with a lot of pockets.
I bought some of the canned premix fuel stuff, tried it out, then kept the cans. I use a funnel and put my own mix in them now. They are one quart round metal cans and fit in the jacket side pockets perfectly, and are also the easiest to pour from of any fuel can I ever used on saws.. And you can put bar oil into one quart old motoroil cans, again,. they go into pockets. Still enough pockets for tools, wedges, an extra loop in a ziplock bag, etc.
then, walk in, saw in one hand, axe in the other.
If I need more than that and need to walk in, I use a wheelbarrow. I'll have it with me anyway to get the rounds out, so whut the heck, you can load it up, extra saws and stuff.
I have a load bearing vest in my emergency prep stuff, but I am thinking of getting another one and modifying it just for cutting.
