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
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
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.

Osprey Renn 65
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.

Osprey Kyte LT 45
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
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.
