Setup and Fitting
Achieving a proper fit is crucial for comfort and load distribution. The Ariel Plus 70 offers extensive adjustability.
1. Torso Length Adjustment
The backpack's torso length can be adjusted to match your back length. Loosen the webbing straps at the top of the shoulder harness and slide the harness up or down along the frame until the hipbelt sits comfortably over your hip bones and the shoulder straps curve over your shoulders without gapping or digging.

2. Fit-on-the-Fly Hipbelt Adjustment
The hipbelt extends and retracts to provide a custom wrap around your hips. Adjust the hipbelt pads by pulling them forward or pushing them back along the main hipbelt webbing until they comfortably cup your hip bones. Secure the main hipbelt buckle and tighten the webbing.
3. Fit-on-the-Fly Shoulder Strap Adjustment
The shoulder straps can also be adjusted for a precise fit. Ensure the straps are snug but not restrictive, allowing for full range of motion. The load lifter straps, located above the shoulder straps, should be tightened to pull the pack closer to your body, transferring weight to the hipbelt.

4. Sternum Strap
Adjust the sternum strap across your chest to a comfortable height and tension. This helps stabilize the shoulder straps and distribute weight.

Operating the Backpack
Packing Your Backpack
Distribute weight evenly, placing heavier items closer to your back and centered. Lighter, bulkier items can go further from your back, and frequently accessed items in external pockets.
Using the DayLid
To convert the top lid into a daypack:
- Unclip the top lid from the main pack body.
- Locate the hidden shoulder straps within the lid.
- Attach the straps to the designated loops on the lid to form a small daypack.

Deploying the Raincover
The integrated raincover is stored in a dedicated pocket, typically at the bottom of the pack. Pull it out and stretch it over the entire backpack, securing it with the elasticized edges and toggle closures to protect your gear from rain.

Maintenance
Cleaning Instructions
To maintain the longevity of your Osprey Ariel Plus 70 backpack, follow these care instructions:
- Hand Wash Only: Do not machine wash or tumble dry.
- Use mild soap and cold water.
- Scrub gently with a soft brush or cloth to remove dirt.
- Rinse thoroughly to remove all soap residue.
- Hang to air dry completely in a shaded, well-ventilated area. Avoid direct sunlight or heat sources.
- Ensure the pack is completely dry before storing to prevent mildew.
Storage

Troubleshooting
Discomfort During Wear
- Issue: Shoulder pain or hip discomfort.
- Solution: Re-evaluate your fit. Ensure the torso length is correct, the hipbelt is centered on your hip bones, and the load lifter straps are engaged. Adjust the Fit-on-the-Fly components for a snug, custom fit.
Pack Feels Unstable
- Issue: Backpack sways or feels off-balance.
- Solution: Check your packing. Heavy items should be close to your back and centered. Utilize compression straps to cinch down the load and prevent shifting.
Difficulty Accessing Items
- Issue: Cannot easily reach frequently needed gear.
- Solution: Plan your packing. Place essential items in hipbelt pockets, side pockets, or the top lid for quick access.
