A couple of years back, we trained a class of Boy Scout leaders to be NRA RSOs. While waiting for someone with keys, one of the leaders motioned to my colleague and said "I just love Bill! He's a walking advertisement for all the latest hiking gear." Sure enough.
Long story short (too late!), the amount of lightweight stuff they have for civvies now is mind boggling! Spend enough money on a lack of weight and you certainly will not be wanting for any accessory/tool.
By 2116, when our military has gone to the current lightweight stuff, civilians will be able to have a 30# pack with a portable house, sauna, flushing toilet, and wood grill.
