Without my Jansport! I own 3 jansport packs: a small daypack, the 55 Klamath, and the 68 Klamath. I borrowed the 55 for my Mt. Hood climb and had to buy one for myself - just to have for such situations when the 68 was a big too big. Used my 68 for Mt. Elbert in Colorado (pic shown). Jansport proves time and time again that comfort is priority. I have carried anywhere from 25-40 pounds in the 55 and 68 and had no issues. Easy to adjust, very durable, roomy and just comfortable all around. My pack for sure! Anywhere from a day trip to weekender camp/climb, to week long camping/climbing trip, I never leave home without my jansport.
