The journey to lightweight is an interesting one. It's about compromise.

As a family we started very heavy years ago and ended up at 68 pounds total for three packs for a week in the mountains. 28, 22, 18. That was the average for the last few sheep hunts we did. Rifle not included in that weight.

The one place I finally compromised was with my integral designs sleeping bag. It was super light and collapsed to about the size of a grapefruit, but after many sleepless nights I added a pound and a half with a deluxe pad and warm down bag. The wonderful sleep was worth every ounce.
A 35* summer bag has no place on the sheep mountains. Lesson learned.

Tony Russ said that a sheep hunter will usually be a bit uncomfortable if weight and bulk are properly addressed. Agreed. Warmth and space come at a premium.
