One more question adding to the thousands more already asked.....I have my entire pack weight at about 12 lbs (about 5.44 kg)......with the 2L water bladder, it's 15.5 lbs (about 7kg). My weight is 120 lbs, so with the water, I'm a bit over the 10% recommendation. I'm a very experienced backcountry camper and I usually carry like 40 lbs but don't do as many miles per day. I've done two "shakedown" walks of 5-7 miles each, and it feels great. I'm thinking I'm in the ballpark with the weight, even though it's 13%. I'd love any opinions or suggestions.
