For weight-conscious ultralight backpackers and thru-hikers, the Osprey Exos Pro 55 is designed for long distance trips on technical trails. The Pro version of this backpacking favourite sheds 20% of the original Exos model, so you can go further and faster than ever before. Ultralight AirSpeed suspension system will keep you supported and move with you, with a ventilated backpanel that separates your back from the pack to increase airflow in hot climates and during gruelling ascents. A fine-tuned adjustment system allows you to tailor the backsystem by up to four inches to find the perfect fit for your frame. The volume can be adjusted too - by removing the single compartment top lid, this pack can shed 80g and 9 litres of capacity for a stripped back hiking setup. For comfort that doesn’t weigh you down, try the Exos Pro 55.
