Looking for something that is tough, reliable, yet blends in with the crowd? For a jacket, check out Carhartt’s Washed Duck Bartlett Jacket. For pants, check out Duluth Trading CO’s Fire Hose Work Pants. Boots can be found cheap at an army surplus store and are just as tough as the more expensive boots you would get at an outdoor sporting store. For an affordable and reliable chest rig, check out the PLA Chicom Type 81.
Whatever you need gear for, you do NOT want to look like you are playing soldier. That looks cool for propaganda, but it is very dangerous when it comes to OPSEC. You will be identified VERY fast.
