Osprey Kestrel 48

Kestrel 48 is Osprey's workhorse rucksack: heavier 420D recycled nylon and a 500D base where the Kestrel LT goes light, a LightWire frame with an AirScape framesheet, and an adjustable torso. The raincover lives in its own pocket at the base, and a zippered sleeping-bag compartment, front shove-it pocket and dual ice tool loops round out a conventional layout. It weighs 4.6 lbs in L/XL (46 L S/M at 4.4 lbs) and is also sold in 38, 58 and 68 L.

Osprey Kyte 48
~$240
Traditional Pack

Kyte 48 is the women's version of the Kestrel, with the same recycled 420D and 500D fabrics and AirScape framesheet but a shorter, women-specific harness. The 48 L WXS/S size weighs 4.1 lbs and the WM/L stretches to 49 L at 4.3 lbs. A stowed raincover, reservoir sleeve, sleeping-bag compartment and fixed lid with an under-lid key-clip pocket keep the layout traditional.

Osprey Kestrel LT 65
~$220
Traditional Pack

The Kestrel LT is new for spring 2026 and simplifies Osprey's long-running Kestrel: an AirScape ridged-foam backpanel over a perimeter wire frame, a sliding harness yoke with five inches of torso adjustment, and an included raincover. It sheds 240-320 g against the standard Kestrel and costs considerably less, giving up about three litres of capacity to do it.

The Renn is the women's-fit Rook, Osprey's entry-level trekking pack. It puts the AirSpeed suspended mesh into a $205 pack by using a heavier 600D polyester shell and a simpler feature set, making it the cheapest route into Osprey's ventilated suspension.

The women's-fit Kestrel LT, described by Osprey as purposefully built for the female frame with narrower shoulders and contoured straps rather than a scaled-down men's pack. Same AirScape backpanel, five-inch sliding harness and included raincover, on the same 28 to 65 L ladder and at the same prices.

Osprey Atmos AG LT 65
~$320
Traditional Pack

The Atmos AG LT is the lighter reworking of Osprey's flagship Anti-Gravity pack. It keeps the suspended-mesh AirSpeed backpanel that made the Atmos famous but swaps the sliding harness for five fixed torso positions and drops to a 210D recycled honeycomb shell, saving around half a pound over the standard Atmos AG 65 and $50 off its price.
