Or: Back to the basics.
With the help of this forum, and the UL one at Backpacker, I have gone from a 40+ Lb pack, to a sub 25 Lb pack. AND, as I now carry less and smaller gear, I can now get all of my gear into my first pack, a Kelty Brisbane. Which weighs 1.5 Lbs less than My Jansport full frame (don't remember the model).
So far it feels great, but that is just walking around the basement with it on
The surprising thing is, I still have room. The surprising thing is, I still have room. Yes I said the last twice, I'm so impressed by it. And, I can fit my water bladder in a pocket, when the bladder is full, with the Jansport, I could only get it in it's pocket when 80% full
I am so headed for a 15Lb pack weight. And, I'm still as comfy in camp as I was with the 40+ Lb, but way more happy on the trail.
Doctari.
