I'm not sure what Ultralight weight is. Last weekend I went for 2 days with a 28lb pack including 40 oz water. I could probably get to 26-27 lbs but why? I have everything I need and am comfortable. I can also cover ground at 2-3 mph at that weight depending on slope gradient. I really don't think saving a couple extra pounds is going to make me faster or able to hike farther.
I used to work with a guy who almost made weight reduction a religion. He literally did cut off his toothbrush handle to cut weight. He wasn't a hunter, just a hiker. If he hunted, he would probably go to the smallest legal gun just to cut cartridge weight.
