My favorite packs all have different criteria. For any list of parameters I only have one pack. I also have an MS Ghost, the design before the one in Jason's video. It takes a beating and keeps on ticking. Also like Jason quite a few of my packs have been discontinued or the new model is significantly different. My goto lightweight pack is a Fanatic Fringe Thompson Peak (9.5oz). Sadly it appears the company doesn't exist anymore.
