As you see from pics, the RuckJack($TBA; March 2009) is a jacket with fast clips that allow it to be easily converted into a rucksack. You had better put a jacket in the rucksack, because you will be cold, I like this suggestion. "'Outdoor sports enthusiast?' When you get changed, convert your RuckJack into a rucksack and store your street clothes in it to keep them dry and clean while you enjoy your favorite outdoor sport!"
