Prepare yourself for a weeklong backpacking trip into Glacier National Park with the Osprey Xenith 75 Backpack. This beefy backpack hauls enough gear to keep roaming the wilderness for a week, while maintaining enough comfort so you can traverse across scree fields or hike up to a glacier lake. Its LightWire peripheral frame suspension provides solid structural support while the Xenith's BioForm 4 CM hip-belt and harness give you a comfortable, supportive, and customized fit. The Airscape back panel allows the load to sit close to your body for balance, while allowing air to flow through mesh to let your sweat dissipate. Multiple pockets allow you to organize your smaller items, including the removable lid that doubles as a daypack for a quick run up to a nearby summit.
