UL - Ultra Light is, to me, a separate class in the hobby we call backpacking
From my personal experience, at or under 30 lbs all-in (food & water) is a great target / level for 98% of all hikers.
yes, takes some money and some planning.
As of right now, at 54 years old there are certain "comfort" levels I am willing to carry, including:
Whiskey or whatever "booze" I choose to carry, I am a section hiker, at the end of the day, nothing washes my single serve SPAM down like some good stuff from the liquor store.
Ditto waterproof bags and separate bags for all of my gear. I like to be organized in life & on the trail, same thing applies to keep my gear DRY
Clothes - I used to carry extra, no more. Lighter, thinner, layers, works for me
Gear - the newer gear does cost money, this is MY hobby, saving up for new gear also works for me. Less is more.
No Cook - again, as a section hiker I am fine with not having any warm food for 10-14 days. eat in town, splurge in the off hiking season. Learned no cook mode from serious thru hikers like Trek and Eric D. If it works for them it defintely works for Del Q
At 220lbs and dropping, a 30 lb pack is X % of my body weight
Looking at Spring 2014 hike, hope to be closing in on 210 lbs...............started this journey 245lbs + body weight and 40+ lb packs.
UL is a matter of perspectivem age and time
