I've seen plenty of best weapon and best place to go threads, but not one with gear. I mean stuff like, tools, armor, clothes, shoes, etc. Make sure its practical though, items you can get ahold of. Hell, even stuff you can make yourself!
Currently, I have a paintball mask equipped with an LED tactical flashlight, and a breathing filter to avoid getting debris in my mouth.
I prefer to wear microfiber urban camo thats not too tight, but fits close. Durable black Nike crosstrainers, carbonfiber impact riding armor, and a black resin-fiber backpack.
Tools I would carry-
A knife with a serrated edge.
A small prybar.
A lockpick kit.
A lighter and matches.
A medical kit.
Several Mp3 players with single portable speakers.
