I have two bags depending on the location.
One has minor items for quick finds:
First aid kit
water
led lamp
pencils
lighter
small first aid kit
notepad
The more equipped bag is for longer treks and doubles as my day hike bag:
Aqua tabs
heavy duty freezer bag
space blanket
dental floss
whistle
compass
Mora Frosts stainless steel
magnesium fire block
matches in safe
metal match
toque
first aid kit for trail
signal mirror
energy bars
water
multitool
socks
small maglite and extra batteries
100' parachute cord bright orange
heavy duty bright orange barrel liner
bandana
extra boot laces
All weighs about 5 lbs and fits in a small but pack. I then also carry my cell and gps and sometimes a camera.
