Cellphone
Wallet (Cash & cards)
SAK (could be one of 3, depending on how I feel - a little tiny one with blade, scissors and file/screwdriver lives on my keyring)
LED light (tiny blue led squeeze light lives on the keyring as backup)
Lighter (disposable)

Jacket pockets usually have a disposable poncho or space blanket

(UK members - tesco have space blanket and disposable ponchos bagged together - were a £1, now down to 25p. Even with the shortcomings of the space blanket, that is too cheap not to pack.)
