Need a pack that can comfortably carry up to 60 pounds? Whether you’re heading out for a weeklong hike at Oak Openings or trekking across Europe, the Osprey Aether and Ariel 65L packs are built for serious adventures.
Zach from Ridge and River is back to walk you through what makes these heavy-hauling packs such top-tier picks—and why they’ve become a favorite among backpackers looking for that perfect blend of comfort, durability, and custom fit.
Built for Big Adventures
The Osprey Aether (men’s) and Ariel (women’s) lines are engineered to comfortably carry heavier loads without sacrificing comfort. While Zach spends more time using the Aether 65L himself, his wife and several friends have tested the Ariel 65L on a range of trails.
If you're planning a multi-day trip and need serious capacity with trail-proven comfort, this line delivers.

Men’s vs. Women’s Fit: Aether vs. Ariel
Though nearly identical in features, these packs differ in fit:
| Feature | Aether (Men’s) | Ariel (Women’s) |
|---|---|---|
| Shoulder Straps | Wider | Narrower |
| Hip Belt | Larger | Contoured for women’s hips |
| Overall Fit | Built for men's body shape | Built for women's body shape |
Zach emphasizes that both are built on the same core design, just tailored for better anatomical fit.
Real Talk: Pros & Cons from the Trail
What Zach Likes:
-
Handles up to 60 lbs. with ease (though he usually stays around 30–40 lbs.)
-
Stays comfortable mile after mile, even under heavier loads
-
Great adjustability lets you dial in your perfect fit
What to Consider:
-
Compared to Osprey’s Atmos/Aura line, the AirScape back panel sits tighter to your back, which might not be ideal for hikers with lower back pain
-
If you prefer a "floating" sensation like the anti-gravity system offers, this may not be the perfect match
Zach’s advice: Try both in-store with weight loaded in, walk around, feel the difference, and see what your body prefers.
Ideal Use Cases
-
Multi-day backpacking trips in places like the Manistee River Trail or Wayne National Forest
-
Weeklong hikes in rugged terrain where load control is critical
-
