Osprey Kestrel 48 Men's

The Osprey Kestrel 48 belongs to Osprey's classic hiking line rather than its ultralight one. The AirScape back panel with ventilated foam and the aluminum-stayed LightWire frame are built to handle heavier loads, and the body uses bluesign-approved 100% recycled 420D nylon with a PFAS-free DWR finish. That comfort and durability come with a weight cost: at 48 L, the pack weighs 2095 g, or about 43.6 g per liter — more than double the ratio of the ultralight Exos Pro line. Access to the main compartment works from both the top and the bottom, and the pack adds a front pocket, two side pockets, dual ice axe loops, and an integrated rain cover. It's hydration-compatible, though no reservoir is included. The Kestrel 48 targets multi-day trekking and moderate thru-hiking where durability and load-carrying take priority over shaving grams — a solid, well-equipped pack for hikers who aren't chasing an ultralight base weight.
