The Osprey Sirrus 44 Women’s Pack is a premier choice for serious female hikers and trekkers seeking a technical, high-performance solution for demanding day trips or lightweight overnights. This pack is engineered with a women-specific fit, ensuring that the harness and hipbelt wrap comfortably around the female frame to provide optimal weight distribution on rugged terrain. At the heart of its design is the AirSpeed suspension system, which utilises a 3D-tensioned mesh backpanel to create a ventilated air gap between your back and the pack, keeping you cool during intense ascents. Accessing your gear is effortless thanks to the top loading design with a secure cinch closure, while a fixed top lid provides extra security for the large compartment. For those who need quick access to essentials, the pack features a hidden side zip to reach the main body without unpacking, and a bottom access point with a collapsible compartment to keep sleeping bags or bulky gear organised. Environmentally conscious adventurers will appreciate that this pack is a bluesign approved product, constructed from sustainable, recycled materials designed to endure years of trail abuse.

Whether you are facing sun or storms, the Sirrus 44 is built to provide cloud-like comfort and uncompromising organisation.

Key Features:

  • AirSpeed suspension: An injection-moulded ladder adjustment system paired with breathable mesh provides superior airflow and a customised fit, with 4 inches of torso adjustability.
  • Comprehensive access: Features a top loading opening with cinch closure, a hidden side zip, and a bottom access point for the collapsible compartment.
  • Integrated raincover: A dedicated base pocket houses an included raincover to keep your equipment dry during unexpected downpours.
  • Strategic storage: Includes a fixed top lid with an underlid zippered pocket and key clip, a large vertical-zip front stash pocket, and dual stretch side pockets for water bottles.
  • Technical attachments: Equipped with a Stow-on-the-Go trekking pole attachment, a single ice tool loop, front panel lash loops for securing extra gear, and removable sleeping pad/accessory straps.
  • Load stability: Features upper and lower compression straps and an adjustable sternum strap to keep your load balanced and secure.
  • Comfortable carry: The padded harness and hipbelt, featuring dual hipbelt pockets, ensure all-day comfort and easy access to small essentials.
  • Hydration ready: An internal sleeve is included to accommodate a hydration reservoir, keeping water easily accessible on the move.
  • Sustainable build: Manufactured with bluesign approved, 100% recycled nylon for a durable and eco-friendly design.
  • Durable Water Repellent (DWR) treatment: Provides water resistance without per- and polyfluoroalkyl substances (PFAS), promoting environmental sustainability.

Due to its 73cm height, it may be too tall for standard carry-on restrictions, which usually limit height to around 55cm, although it can often fit if not fully packed.

The hydration sleeve can accommodate a laptop, but it is not specifically designed for it, and protection is minimal.

Yes, it has a 4-inch (approximately 10cm) adjustable torso length, tailored for a woman's frame.
