I agree with teacher. This seems like an awful lot of stuff for hiking. If you're looking for suggestions, maybe this can help us help you:

What type of environment and seasons do you hike in?
How long do you usually stay out? Do you cut a lot of firewood?
Anyone else with you? Is there a lot of redundancy with them?
Are you accident prone? I only ask because there may be a reason
you carry "this much." I know I always burn myself cooking (but
only outdoors, for some reason).


Just as a quick example, in my day hike kit:
Camelback-style bag, with 70oz. bladder
1 GI canteen
1 LC-2 GI first aid kit (with my stuff in it)
PSK.
Extra matches, LED light, and a space blanket
Pocket knife: usually my Benchmade Griptilian. A Ka-bar 5" might
be taken on a long trip.
50' of paracord.
A couple power bars, maybe some trail mix.
Vest, 1 trash bag. Rain jacket if it's looking likely.
My clothes: boonie hat, shorts/pants, hiking boots, usually a
Under Armour type shirt.

BTW, I really like your bag. Can you point out where you got it? Thanks!
