Last summer, when I was hitchhiking in Colorado, I met a 63 year old hiker who gave me a ride. He taught a course on Ultralight Backpacking at the local college. Bob said that the easiest way is go ultralight was to scrape up $1250, go to the zpacks.com website, and order their most popular cuben fiber pack, solo tent, and down sleeping bag. This gets the “Big Three” on your back for total weight of three pounds. Expensive, but efficient.
For the rest of us, it’s best to start with keeping the big 3 under 10 pounds, which would lead to a fully loaded backpack of 15-20 pounds if you leave that Rambo knife at home.
Once you have cut the weight on your Big 3, you enter the “ we pack for our fear” zone. Anxiety about what might go wrong on a hike may lead to placement of unnecessary items in that light pack. For example, I once saw another backpacker pull a cast iron two foot long lawnmower blade from his pack and place it by the side of his sleeping bag at bedtime. I asked him about it and he said, “ Wild hogs here in Georgia can attack you when you sleep.” I used to carry a heavy ankle brace, “just in case” , but after lugging around-unused for 3,700 miles I now leave it at home.
I hike with three pair of thin socks, two for walking in, one for sleeping. Ultralight hikers don’t generally carry spare clothing like underwear. Some give up long pants in the warmer weather, adding thin wool tights and rain pants if it gets too cold.
Another popular option to ditch weight is to go stoveless, and forget the cooking pot as well, opting for foods that don’t require cooking, or that can be rehydrated with water in a plastic container.
A Katadyne-type pump filter for water purification is not a typically in an ultralight pack- instead we see the Aqua Mira solution, or a Sawyer Squeeze gravity system.
The best resource for a quick lesson in learning about ultra and lightweight backpacking is the book “Lighten Up ! A Complete Handbook for Light and Ultralight Backpacking” by Don Ladigin. It’s inexpensive and filled with all you need to know.
Of course if you have $1250 bucks, you can get there quickly, but I would rather take that amount and use the money for a one- month backpacking trip.
