I just built a quick day kit for my quad....for here in the sub-Arctic. Hope the info is useful. No trees or cell service 2 kms from town. The kit is in a small tool bag so it doesn't take up any room. Easy to grab when going out the door.
Extra gloves, socks, woolen hat
Tools, wrenches etc
Spare plug, removal wrench, electrical tape
12 volt air pump, gauge, stem remover
Hunting knife, lighter, extra tow rope
Nutrition bars -3 or 4
2 folded plastic bags
First aid kit...mainly band aids
Emergency beacon, blankets, sleeping bag
Canned beans and opener.
Quart of oil
