Osprey Aether Backpack - 55L - Black

While the Aether 55 has an adjustable torso, you can get an initial fit by measuring your torso length from the C7 vertebra (the bony protrusion at the base of your neck) down to your iliac crest (the top of your hip bone). Adjust the pack's torso length to match this measurement, then fine-tune it with a loaded pack.

The pack is made from bluesign-approved nylon with a PFC-free DWR coating for water resistance. It also includes an integrated raincover for complete waterproof protection during wet conditions. The pack itself is not fully submersible waterproof.

Osprey designs the Aether 55 to comfortably carry heavy loads. While there isn't a strict maximum weight, the pack's highly adjustable suspension system is optimized for loads typically associated with multi-day backpacking, often ranging from 30-50 pounds (13-22 kg), depending on your comfort and physical fitness.

Yes, the Aether 55 typically features various attachment points, compression straps, and tool loops for securing items like sleeping pads, trekking poles, ice axes, or tents to the exterior. Always ensure external attachments are secure and don't interfere with your balance.

Spot clean with a damp cloth and mild, non-detergent soap. For a more thorough cleaning, hand wash the pack in a tub of lukewarm water. Do not machine wash or tumble dry. Air dry completely in a well-ventilated area away from direct sunlight.

Bluesign approval indicates that the textile manufacturing process has met stringent environmental and safety requirements, minimizing impact on people and the environment by reducing resource use and eliminating hazardous substances.

Re-adjust the `Fit-on-the-Fly` Shoulder Straps and Hipbelt. Ensure the torso length is correctly set for your body. The hipbelt should bear most of the weight, not your shoulders. Check for proper sternum strap placement.

Repack your gear, ensuring heavier items are placed closer to your back and centered between your shoulder blades. Distribute weight evenly side-to-side. Tighten load lifter straps to bring the pack's weight closer to your body.

Ensure the raincover is fully deployed and securely wrapped around the entire pack. Check for any tears or holes in the raincover. If damaged, a replacement may be needed.

Clean zippers with a small brush to remove dirt and grit. Apply a silicone-based zipper lubricant or a small amount of beeswax to the teeth to improve movement.

While the injection-moulded backpanel offers support, some sweat is natural. Ensure all straps (shoulder, hipbelt, sternum, load lifters) are properly adjusted to allow for maximum airflow and prevent the pack from pressing too tightly against your back.
