Our Verdict
The Osprey Ariel 65 remains a longstanding staple in the backpacking world. Built for hikers who prioritize support, durability, and a highly customizable fit, this pack makes 35+ pounds feel more manageable than lighter packs carrying less weight. Its standout feature is its exceptional adjustability, with easily customizable shoulder straps, hip belt, and torso length that accommodate a wide range of body types. With dense cushioning and a thoughtfully shaped hip belt that transfers weight effectively, this pack is particularly comfortable when fully loaded. While the pack's rigid structure and heavier build can limit mobility and ventilation, it's designed to handle demanding trips with ease.

The highly adjustable fit across the torso, shoulder straps, and hip belt keeps this pack comfortable when fully loaded. This allows for a dialed-in, personalized fit that accommodates a wide range of body types.
The durable construction and well-cushioned contact points keep the Osprey Ariel comfortable over time. The materials are built to last, and the padding helps prevent pressure points during extended wear.

Dislikes
The Ariel 65 is heavier than many modern backpacking options. That extra weight becomes noticeable quickly, especially for anyone already accustomed to lighter, more streamlined setups.
The rigid frame of this backpack can limit movement on more technical terrain. While it provides excellent support under load, it can feel restrictive when scrambling through difficult sections of trail.
The side pockets are tight and not very user-friendly. When the pack is fully loaded, fitting or retrieving items like water bottles can be awkward and inconvenient.

Should You Buy the Osprey Ariel 65?
We recommend the Osprey Ariel 65 for backpackers who regularly carry heavier loads and want a pack that prioritizes support – it's especially well-suited for extended trips and gear-heavy adventures. If you're more focused on comfort, this pack will serve you well. However, fast-and-light hikers will want to look elsewhere.
What Other Backpacking Backpacks Should You Consider?
The Gregory Deva 60 is very similar to the Ariel 65, but it's more comfortable. Even though the Ariel is a long-standing design, Osprey makes a number of much better packs, including the smaller-framed Gregory Maven 58, the budget-friendly Renn 65, and, dreamiest of all, the smooth-riding Eja 58.
