I use a Gregory Baltoro 75. I do not personally look for ultralight gear. I have spent the last 8 years in the military and my ruck is a min of 80lbs so on the civilian side I say learn to carry more weight well. The baltoro is incredibly comfortable and strong, the quality is outstanding and it will last for years. The pocket design makes accessibility and organization excellent. What I look for in gear is not crazy weight savings but simply space savings. I am also hard on my equipment and it is used much more frequently than your average joe, so durability is key.
