I don't do self-supported touring. My days of backpacking cured me of the desire to carry my house and furnishings. I went ultralight for my last two seasons of backpacking so I know how to reduce mass and shop for light gear. Nonetheless, my load for Ride Idaho was almost 50 pounds divided into two large duffles.
When I got home, I carefuly weighed my entire kit, item by item. Rounding up to whole pounds conservatively, here are the rough numbers:
1. Tent: 7#
2. Sleeping pads: 5#
3. Chair: 6#
4. Sleeping bags: 5#
5. Bike clothing: 4#
6. Camp clothing: 5#
7. Personal effects and toiletries: 5#
8. Junk and accumulated junk: 5#
The tent will be with me till it dies, no savings there.
I carry two self-inflating pads to create enough neck height becasue I'm a side sleeper. I might be able to reduce that using newer technology but that's at least $130.
The chair is required although there may be lighter units. An unexpected bonus of this particular chair form REI is I can pull it inside the tent and read in comfort during a storm or in heavy bugs. A lighter chair is not as comfortable and might be $50-100.
I carry two down bags, a one- and a two-pounder. Together they can handle any temperature down to about 20F. This proactice is not likely to change since a 20F down or synthetic bag is about the same mass and reduces the flexibility and comfort.
A full riding kit is about 16 ounces so I could reduce that mass by leaving one set of bike clothes at home and doing more laundry.
Camp clothing includes my rain and cold riding gear as well as bug and sun protection clothing and shoes. Not much can be elliminated but some lighter versions are available. However, none of this gear needs to be replaced.
There are maybe two full pounds of personal effects, toiletries and other silly stuff that can be left at home. This costs me nothing except some entertainment.
The useless junk one packs and stuff one acquires along the trip can add up quickly. That seems to be the only major mass savings I can control.
A fearless inventory of my gear results in savings of less than 5 pounds but that's roughly 10% of the total so that's not negligible. Going deep into deprivation mode, I can leave almost 10 pounds at home. I am not replacing any equipment that is not damaged.
ONe of the major benefits of my ultralight backpacking kit was the total lack of superfluous stuff. Setting and striking camp was easy and quick because there was nothing to lose or misplace. I'm just glad someone else is carrying this stuff for me.
