I have not done any major thruhikes yet. I am to do a Thruhike on the Tahoe Rim Trail (TRT) this summer. My longest stretch yet was only 4 days. This summer will be 8. Any way, I was thinking of getting my pack size down to 2300 CI, with and expansion collar to 3000-3300 CI. But, before I go off designing and sewing I was wondering what people thought was an adequate AT UL Thruhiker pack size. With your answer please state why, and your base weight or FSO which ever just let me know which you are giving. Thank you.
Oh, currently I have about a 3300 CI pack, but it is never full. Again I have not done anything real long. My 10 day trip in Panama didn't even get the pack full with extra shoes, slippers, and 6 days of food. Didn't have my cookware, but that is really small and could have fit that too.
