Osprey Ariel Plus 70L Women's Backpack – Adjustable Fit, DayLid, Raincover

The Osprey Ariel Plus 70L is a large-volume, women’s-specific backpack designed to support multi-day treks and gear-heavy adventures. A stronger LightWire frame keeps the pack stable and close to your body, helping you maintain balance on exposed ridges or technical trails. With a generous 70-liter capacity, there is room for essentials, extra layers, and bulky gear without sacrificing mobility. The design centers on a fit that adapts to real bodies, so you can move with confidence mile after mile.

To dial in comfort, the Fit-On-The-Fly system provides three adjustable contact points: the hipbelt, the shoulder straps, and the torso length. This combination enables a precise, personalized fit for a range of body shapes and sizes, reducing pressure points and distributing weight more evenly as you climb, descend, and pivot on uneven terrain. The result is a closer-to-the-silhouette feel that can help you stay efficient during longer days on the trail.

Flexible, real-world features

• Custom Fit on the Fly: adjustable hipbelt, shoulder straps, and torso length for a precise, personalized fit.
• Stable load handling: strengthened frame keeps weight near your center of gravity for improved control on rough sections.
• Removable top lid converts to DayLid: adapt the pack for short forays without carrying the full load.

Storage and access are designed with practical packing in mind. The top lid can become a lightweight DayLid for quick side trips, while a dedicated sleeping bag compartment with a removable divider helps you separate sleep gear from everyday items. The overall layout supports organized packing so you can locate a rain shell, mid-layer, or map without unpacking everything.

• Sleeping bag compartment with removable divider keeps sleep gear separate from the rest of your kit.
• Zippers and pockets provide quick access to layers, hydration, or electronics when you’re on the move.

Weather-ready and responsible materials

The Ariel Plus 70L includes a raincover to protect gear in wet conditions. The fabric is Bluesign-approved and treated with a PFAS-free DWR, aligning with contemporary sustainability and performance expectations without compromising on protection.

Specs and real-world use

Dimensions are 29.5 inches high by 15 inches wide by 13.4 inches deep, with a weight of 5.54 pounds. This balance of capacity and weight makes it a viable option for weekend getaways or longer itineraries where space and weight matter.

In the wild

Imagine loading the Ariel Plus with a compact tent, stove, and layers for a three-day trek. The load stays closer to your body through rocky stretches, while the DayLid option and organized pockets help you stay nimble as you switch from trail to camp to town.
