Meet the Osprey Sirrus 24 Hiking Backpack (2026) — a daypack engineered for cloudlike comfort, exceptional ventilation, and trail-tested durability. Designed with a women's-specific fit, it hugs the contours of your torso for all‑day support while offering streamlined storage that's easy to reach on the move. Dual front panel zips unlock quick access to gear, so you’re never digging through the main compartment when time matters on the trail.

All the Right Storage, Where You Need It

Stay organized with a thoughtfully designed layout that keeps essentials at your fingertips. A wide, dual‑zip access to the main compartment makes packing and access a breeze. A zippered top pocket with a key clip secures small items, while a compact front panel pocket is perfect for sunglasses or a phone. The large vertical‑zip front stash pocket is ideal for extra layers, and two hipbelt pockets keep snacks, a compass, or a small GPS within arm’s reach. Stretch side pockets safely hold water bottles or quick‑access items on the move. Inside, an integrated hydration sleeve features a hose routing port and Hydraclip for easy hanging of your reservoir.

AirSpeed™ Suspension for Breathable Comfort

The Sirrus 24 pairs a LightWire perimeter frame with an open‑mesh backpanel to deliver superior load stability and ongoing cooling airflow. This combination minimizes heat buildup, even on climbs, while maintaining a comfortable, secure carry as your trail day unfolds.

Ready for Changeable Conditions

Weather-ready reliability comes standard with a raincover stored in a dedicated bottom pocket, so you’re prepared when clouds roll in or a sudden shower hits. All materials and components meet bluesign® PRODUCT standards, reflecting a commitment to environmental responsibility without compromising performance.

Versatile, Thoughtful Details

• Upper and lower side compression straps to keep the load compact and balanced
• Adjustable sternum strap with magnetic closure for quick, secure adjustments on the move
• Stow-on-the-Go trekking pole attachment for fast stow and grab during breaks
• Ice tool loop with bungee tie-off for light mountaineering versatility
• Front panel lash loops to attach extra gear when conditions demand more capacity

Why This Pack Shines for Day Hikes

Ideal for weekend warriors, backyard-to-boulder days, and everything in between, the Sirrus 24 balances capacity with a compact footprint. It’s the kind of pack you’ll reach for when you want reliable organization, quick access to water and layers, and a fit that feels custom‑titted rather than generic. The combination of a ventilated suspension, strategic pockets, and a rain-ready shell makes it a practical partner for variable weather and diverse trails.
