I need your help. I have been backpacking, not all that seriously for the past few years with this old, uncomfortable external frame, purple pack (gag me) and it is time for a change. I am looking for a lightweight pack, hopefully not above $300, that will be good for 2-5 day trips. Ill be going to Appalachian State next year, and a 3500+ size pack was suggested in case I do some cold weather backpacking. Suggestions? What do you think?
