There are a couple of things to bring your pack weight down. Big Agnes Fly Creek UL2 at 2 lb 7 oz including ground sheet. Your sleeping can be 16 oz (see Nunatakusa.com for details). I am 64 years old and carry 14 pounds on my back (including food) and 5 pounds on my chest including water (see Ribzwear.com for chest pack). If I would eliminate a couple of items, I would be at the 12 lb area. Best of luck.
