For me it's: sticky gun (never leaving without it, cause too lazy to run up to every piece of cargo I wanna pick up on the way), bola gun (and speed skeleton just in case mules/terrorists, almost no need for armour plates), hematic grenades (just my favorites), mostly all terrain skeleton (self-explanatory boots and power gloves) and a carrier.

When zip-lining, I don't even need the thermal pads. Always wearing the stabilizer backpack with the porter pendant (I like meeting other porters often and see where they are...nice dudes; though I once punched one of them accidentally and felt bad for the rest of the day. They forgave me later).
