Tripod, spotter, 40 oz of water, 2 knives, first aid kit, headlamp, backup AA light, nitrile gloves, rangefinder, small camera, multi tool, maybe a small camp axe, lighters, 100' of paracord, 5 extra rounds of ammo, 2 Clifbars, a bag of trail mix, 6oz of jerky and a few small miscellaneous items. (A 4oz flask of Willetts Small Batch 4yo Rye might be in there somewhere as well....in a titanium flask because, you know, I'm really trying to save weight damnit!! LOL!)) All packed in one of the older Camelbak HAWGs with 4 additional pouches, it comes in at 17lbs. This is for 4-8 mile, all-day out-and-backs for the most part, but I usually don't go all that far. Gotta have the gear at the ready though.
