Maybe more information than you wanted, but I've had a thread going for over a year on another forum on what to carry for a mountain daypack list. Here is where I'm at after getting everyone's input. It is much more thorough and lighter than my original list. I also got a postage scale to verify weights last spring, and all weights are rounded to the nearest ounce.

-Benchmade folding knife 4oz

If I added right, with this list I pack 248oz or 15.5lbs not counting the pack itself. I don't think that weight is to bad including water. I still would like to switch to a separate tarp and rain gear, but the poncho will work for now. I'd like to get a Kifaru paratarp, but haven't spent the money yet.
Also on my person I carry binoculars, 4 rounds extra ammunition and a 4oz Altoids tin with a firesteel, tinder packets, striking surface, waterproof matches, oven bag (for water), and water purification tablets are carried in my pocket.
