This pack is great! I am relatively new to backpacking and I purchased my Exos 58 (large 61L) for a recent trip to Europe to travel around for several weeks. Fully packed it weighed in about 37-40 lbs. and handled it beautifully. I'm about 6'1 and had no problems with sizing or comfort. My friend actually wanted to carry my pack over her backpack because it carried the weight so well.
