Why We Like The Osprey Exos Pro 55L Backpack
To optimize weight and comfort for our longest through-hikes, Osprey fine-tuned the Exos to make the Exos Pro 55L Backpack. This ultralight design sheds nearly a pound off the original and a few more ounces when the lid is removed. Supportive details from the inside out allow us to manage a week's load and adjust capacity, balance, and organization as needed.
Osprey's comfort-focused carrying system starts with their AirSpeed suspension. This tensioned-mesh back panel offers a supportive fit and provides plenty of space between our backs and the pack for cool airflow on our longest hikes. Silicone print at the lumbar helps the hip belt grip more steadily, so the dynamic foam belt can stretch and move with our hips without slipping up our backs. Spacer mesh shoulder straps are ventilated as well, keeping air moving all around our torsos.
