Osprey Tempest Pro 40

Tempest Pro 40 is the largest of Osprey's women's fast-and-light packs, sized big enough for an overnight with a compact kit. A LightWire peripheral frame and sliding-yoke torso adjustment carry 15-30 lbs, while the BioStretch harness and hipbelt move with the body. It weighs 2.9 lbs in WM/L (2.7 lbs in the 38 L WXS/S) and adds a floating lid that the 20 and 30 L versions lack.

Osprey Talon Pro 30
~$250
Daypack

Talon Pro 30 takes the Talon's fast-hiking layout and rebuilds it in Nanofly, a nylon and UHMWPE ripstop that resists abrasion at a lower weight. A wide bucket opening replaces the lid, a BioStretch harness and continuous lumbar-to-hipbelt wrap keep it stable on scrambles, and Osprey rates it for 15-25 lbs. It comes in S/M (28 L) and L/XL (30 L), with 20 L and 40 L siblings.

Osprey Talon Velocity 30
~$215
Daypack

Talon Velocity 30 is a frameless pack with a running-vest-style harness, so the load splits between the chest and back rather than hanging from the shoulders. Two 500 ml soft-flask pockets, a zippered phone pocket and a helmet-capable front stretch pocket sit where they can be reached on the move. It closes with a top cinch rather than a lid and weighs about 2.4 lbs in S/M.

The Manta is Osprey's hydration-specific hiking pack and ships with a 2.5 L Hydraulics LT reservoir, a magnetic bite-valve attachment on the sternum strap and a dedicated reservoir sleeve. It uses the same AirSpeed suspended mesh as the Stratos, so the price covers both the suspension and the bladder.

The Stratos 24 is the Talon's ventilated sibling — a full suspended-mesh AirSpeed back panel, a real perimeter frame, and an included raincover in a 24-liter day hiker. The women's version is the Sirrus 24.

The Sirrus is the women's-fit Stratos and the ventilated counterpart to the Tempest: a suspended AirSpeed mesh panel rather than contact foam, plus an included rain cover and a heavier 100D x 210D honeycomb shell over a 420D base. It is the day pack in Osprey's women's line for hot weather and long days.
