When I do light touring its without any rack. and since my bags are pretty full, a camelback is really usefull. tube, tools, water, chapstick, bug spray, wet wipes, pocket knife, map, some food, phone. I take a couple light straps to lash something onto it if needed, like a gocery sack with food for the night. About sixty to eighty mile days, with one day of one hundred twenty eight miles. Two liter bladder, along with several bottles and I have still almost run out without anywhere to refill, so its nice.
