Osprey Manta

The Osprey Manta 34L men's hiking backpack includes a 2.5L Hydraulics reservoir, AirSpeed tensioned mesh back panel, integrated rain cover, and Osprey's LidLock helmet attachment — a purpose-designed day hiking and trail running hydration pack for hikers who want a single pack that covers water, gear, and weather protection across full-day mountain outings.

Osprey Manta 34L: AirSpeed Ventilated Back Panel with Hydraulics Hydration

The AirSpeed back panel is the defining feature of the Manta line — a tensioned mesh back system that creates a continuous air channel between the pack body and the wearer's back across the full torso contact area, eliminating the sweat-soaking back contact that makes conventional pack frames uncomfortable during aerobic hiking in warm temperatures. At 34 liters, the Manta carries enough volume for full-day hikes with multiple layers, food, first aid, and navigation gear alongside the 2.5L reservoir — covering the supply requirements for 8 to 12-hour trail outings without being too large for the efficient pack movement that technical terrain demands. The integrated rain cover deploys in seconds without the delay of digging through the pack during weather transitions.

• AirSpeed tensioned mesh back panel — continuous airflow across full back contact area
• 2.5L Osprey Hydraulics reservoir included with MagLock magnetic tube attachment
• 34-liter capacity for full-day hikes with layers, food, first aid, and navigation gear
• Integrated rain cover for immediate weather protection without extra pack weight or searching
• Stow-on-the-go trekking pole attachment for hands-free pole carry on technical terrain

At $342.99, the Osprey Manta 34L is the premium day hiking hydration pack for serious hikers who spend full days on technical mountain trails. The AirSpeed ventilation and complete included system — reservoir, rain cover, and pole carry — justify the price over basic packs for users who prioritize all-day comfort and weather readiness on every outing.
