Now that the PLB has been mentioned, get yourself a good way to carry the kit so if you go down, you aren't separated from the kit. Personally, I'm looking at: Switlik HV-35MOD Air Crew Vest


Pick and choose the pockets you need/want to carry your kit, but this way the kit is on you always. Not in a bag that ends up who knows where after impact. If you are alive and conscious, the kit is right here (touch torso).

* Your PLB goes in a pocket accessible by either hand.
* One or two knives of your choice. I go with a strong locking folder (RSK Mk 1) and a Swiss Army Knife with a saw. . . I may have a third knife in my pocket. . .
* A lighter or two on opposite sides of the vest.
* Signal mirror and whistle.
* An energy bar or two.
* A DR Pocket Survival Pak

Suitable clothing for the climate is assumed. In the PNW, I'd have a small nylon tarp, wool blanket and paracord to build a makeshift shelter or just wrap up. This would be in a separate bag, (back of seat maybe?)

Edit: Looking at that picture, I wonder if a KleenKanteen would fit where that air bottle is located on the vest. . . hmmm
