Osprey says:
The Talon 55 was designed with ultralight multi-day adventures and travellers in mind. An injection-moulded AirScape™ backpanel and a continuous-wrap harness and hipbelt allow the pack to move with you when navigating demanding terrain. This streamlined pack features a top-loading main compartment, a separate sleeping bag compartment with removable divider, hydration reservoir sleeve, dual zippered hip pockets, and attachment points for ice axes and trekking poles. Constructed with high-quality bluesign®-approved recycled high-tenacity nylon with a PFC-free DWR coating.
