A few items I like also
Mammut S-lite headlamps. With a lithium battery they weigh 1.7oz, and use a AA battery like my GPS and camera. I carry one in my daypack survival kit as a spare and one in my hunting gear.
Havalon Barracuta knife. Most people prefer the smaller Piranta, and I like to carry one of those also for caping. For quartering or boning though I like the bigger knife. I also like that I can use either skinning or boning blades with it.
I have a little survival/first aid/repair kit I always throw in also, I take it in whatever pack or fishing bag I'm carrying. My licenses go in it so I don't forget either of them. The items that need extra water protection are in a ziplock, then it is all stuffed into a mesh bag. Here is what it has evolved to currently. I could eliminate some of these items when carrying camping gear, but I carry them anyway. I may get caught away from camp and want them in my daypack.
Basic Full-time daypack kit (1lb 7oz)
-stainless steel water bottle (wrapped in camo cloth tape for silence and to eliminate reflection)
-spare wool socks
-Adventure medical heatsheets bivy (the 3.8oz one)
-cheap mylar space blanket (mainly for a fire reflector)
-bandana (red for signal, pre-filter water etc)
-Mammut S-lite headlamp (1 AA lithium battery, 60hr life, 2oz) (this is part of the kit, and in addition to the second one I count as hunting gear)
-fire kit: firesteel, lighter, vaseline coated cotton balls in Menthos container, 4 wetfire cubes
-50ft roll 2" duck tape
-small bottle superglue
-frontier water filter straw
-10 tablets potable aqua water purifier
-30yds 152lb bank line
-15yds 350lb bank line (great for boot laces)
-25ft bright yellow paracord
-blank CD (signalling)
-little bag with a dozen 45lb 18” cable fishing leaders & 30ft 25lb fishing line, 20ft 10lb fishing line, 12 hooks, repair needle (weighs 1.2oz)
Medical: (stop bleeding, make splints)
-quick clot sponge
-1 roll hot pink vetwrap (bandaging with duck tape, marking trail, etc)
-small tube neosporin
-4 3"x3" gauze pads
-6 pills immodium
-2 pills claritin
-1 packet sunscreen

-4 safety pins
-1 antiseptic towlette
The little kit with the fishing stuff, leaders, and needles isn't really necessary in the mountains probably, but I just leave it in everywhere. It only weighs 1.2oz and I amaze myself sometimes what I can rig up with some fishing line, super glue, a repair needle, and some duck tape to fix things.
