I've been looking at almost every ultralight framed pack i could find, i seem to really like the ones from osprey. From what i have heard from the ultralight community it is best to get one that's not too big s your ot tempted to fill it up and therefore possibly add extra weight. My trips will tend to be anywhere from a weekend to a whole week. I also plan on using this pack for a thru hike of the Tahoe Rim Trail this summer, gunna only put a weeks worth of gear in at a time.
anyway i am debating betwwen the exos 46 and the exos 58. please help.
