What Does AG Mean in Osprey Backpacks? Unveiling the Anti-Gravity™ Secret
The key to Osprey’s exceptional comfort lies in their AG, or Anti-Gravity™ suspension system, a revolutionary design that distributes weight evenly and creates a body-hugging, nearly weightless feel. This advanced technology enhances comfort and allows for unparalleled ventilation, making even the heaviest loads feel manageable.
Understanding Osprey’s Anti-Gravity™ Technology
Osprey’s AG system is more than just padding; it’s a comprehensive approach to load carriage that integrates several key elements to create a superior wearing experience. It’s not simply about comfort; it enhances performance and reduces fatigue during long hikes or travels.

Key Components of the Anti-Gravity™ System
The AG system comprises several interconnected elements, each contributing to its overall effectiveness:
- Suspended Mesh Backpanel: This is the foundation of the AG system. A highly breathable mesh is stretched across a frame, creating space between the pack and your back for maximum ventilation.
- Seamless Hipbelt Integration: The hipbelt is directly connected to the mesh backpanel, ensuring a seamless transfer of weight from the pack to your hips, where it’s most efficiently supported.
- Adjustable Torso Length: The AG system allows for precise torso length adjustment, ensuring a custom fit for optimal comfort and load distribution.
- Lightweight Frame: A lightweight but strong frame provides structure and support, preventing the pack from collapsing or sagging, even when fully loaded.
Benefits of the Anti-Gravity™ Suspension
Choosing a backpack with AG technology provides significant advantages:
- Enhanced Comfort: The suspended mesh and seamless hipbelt integration dramatically reduce pressure points and hot spots, resulting in a more comfortable carry, especially on long journeys.
- Superior Ventilation: The space between the pack and your back allows for maximum airflow, keeping you cooler and drier in hot and humid conditions.
- Improved Load Distribution: The AG system distributes weight evenly across your hips and shoulders, reducing strain on your back and improving balance.
- Increased Efficiency: By reducing fatigue and discomfort, the AG system allows you to hike further and carry heavier loads with greater ease.
Which Osprey Packs Feature the Anti-Gravity™ System?
Osprey offers AG technology in a variety of packs, catering to different needs:
- Atmos AG/Aura AG: These are classic hiking packs designed for overnight and multi-day trips.
- Exos/Eja: Lighter weight options that still provide excellent support and ventilation. While not the “full” AG system, they incorporate suspended mesh backpanels for similar benefits.
- Levity/Lumina: Ultra-lightweight packs, prioritizing weight savings but still offer excellent comfort for their weight class. Again, these offer a similar suspended mesh technology without the full AG designation.
Properly Adjusting Your Anti-Gravity™ Backpack
To maximize the benefits of the AG system, proper adjustment is crucial:
- Load the Pack: Fill your pack with a representative load to simulate real-world conditions.
- Loosen All Straps: Before putting the pack on, loosen all straps, including the shoulder straps, hipbelt, and sternum strap.
- Position the Hipbelt: Place the hipbelt so that it sits comfortably on your hipbones, with the padded portion wrapping around your hips.
- Tighten the Hipbelt: Snug the hipbelt down firmly, transferring the majority of the weight to your hips.
- Adjust the Shoulder Straps: Tighten the shoulder straps until they sit comfortably on your shoulders, but don’t overtighten them. The shoulder straps should primarily provide stability, not carry the weight.
- Fine-Tune the Torso Length: Use the adjustable torso length feature to dial in the perfect fit. The goal is to have the shoulder straps follow the natural contour of your shoulders without creating pressure points.
- Fasten the Sternum Strap: Buckle the sternum strap and adjust it to a comfortable position. The sternum strap should help stabilize the pack and prevent the shoulder straps from sliding off your shoulders.
- Use Load Lifter Straps: Adjust the load lifter straps to pull the top of the pack closer to your body. This will help distribute the weight more evenly and prevent the pack from sagging.
Common Mistakes When Using Anti-Gravity™ Packs
Avoid these common pitfalls to ensure optimal comfort and performance:
- Over-Tightening Shoulder Straps: This shifts the weight from your hips to your shoulders, causing fatigue and discomfort.
- Incorrect Torso Length: This can lead to improper load distribution and pressure points.
- Ignoring the Hipbelt: Failing to properly tighten the hipbelt defeats the purpose of the AG system, as the weight will not be efficiently transferred to your hips.
- Overloading the Pack: While the AG system can handle heavy loads, exceeding the pack’s recommended weight limit can compromise its performance and durability.
What is the primary advantage of the Anti-Gravity™ suspension system?
The primary advantage of the Anti-Gravity™ suspension system is its ability to provide exceptional comfort and ventilation by suspending the pack away from your back and distributing weight evenly.
Is the Anti-Gravity™ system suitable for all body types?
Yes, the AG system is designed to accommodate a wide range of body types thanks to its adjustable torso length and customizable fit features.
How does the Anti-Gravity™ system improve ventilation?
The suspended mesh backpanel creates space between the pack and your back, allowing for maximum airflow and reducing sweat buildup.
Can I adjust the Anti-Gravity™ system while hiking?
Yes, minor adjustments to the shoulder straps, hipbelt, and sternum strap can be made while hiking to optimize comfort and fit as needed.
What happens if I don’t adjust the hipbelt correctly?
If you don’t tighten the hipbelt properly, the weight of the pack will be primarily supported by your shoulders, leading to fatigue and discomfort.
How much weight can the Anti-Gravity™ system comfortably handle?
The amount of weight the AG system can handle depends on the specific pack model, but it’s generally designed to comfortably carry loads of up to 40-50 pounds for hiking packs like the Atmos/Aura AG.
Is the Anti-Gravity™ system waterproof?
The AG system itself is not waterproof, but many Osprey packs with AG technology come with integrated rain covers or are compatible with aftermarket rain covers to protect your gear from the elements.
How do I clean my Osprey pack with the Anti-Gravity™ system?
Spot clean your pack with a mild soap and water solution, paying particular attention to the mesh backpanel. Avoid using harsh chemicals or detergents, as they can damage the materials.
Does the Anti-Gravity™ system make the pack heavier?
While the AG system does add some weight compared to simpler suspension systems, the improved comfort and performance it provides often outweigh the slight weight increase.
What is the difference between the Atmos AG and the Aura AG packs?
The Atmos AG is designed for men, while the Aura AG is designed for women, with specific features like shoulder strap shaping and hipbelt contours tailored to the female anatomy.
Are there any disadvantages to the Anti-Gravity™ system?
Some users may find the suspended mesh backpanel less stable for scrambling or off-trail travel, and the system can be slightly bulkier compared to packs with simpler suspension systems.
