i recently started backpacking and i have to say it is something i plan on doing all i can in the future. i plan on section hiking the AT with a few friends that are equally as excited as i am. i have purchased some start-out gear that is very inexpensive. after my last outing i developed a hernia and had to have surgery. all is better now and i am dreaming of getting back out there. the hernia is made aware that a 40 lb pack is a little heavy for a 2 night stay. i am working on shaving lbs and i will buy gear as i have money. i will purchase quality gear when i can because i don't want to have to constantly upgrade. from the posts on this site that i have read it seems like i should start with a sleeping bag first. does anyone have any suggestions on a bag that is ultralight, compact and durable?
