The pack I have always used backpacking is a Dana Designs Terraplane LTW. So with a thru hike planned for this year I knew I need to get a smaller lighter pack. I just saw a Millet Prolighter 42 Plus on Steep and Cheap and I pulled the trigger. (82 bones shipped) Does anyone have any experience with this pack or Millet packs? Is this going to be big enough?

Thanks,
Brenton
