Setup and Adjustment
1. Adjusting the ActivLift Harness System
The ActivLift harness system allows for precise torso length adjustment to ensure a comfortable and stable fit, crucial for carrying heavy loads over long distances. Proper adjustment distributes weight effectively across your hips and shoulders.
- Measure Torso Length: Use a flexible tape measure to find the distance from your C7 vertebra (the most prominent bone at the base of your neck) down to the top of your hip bones (iliac crest).
- Loosen Adjustment Straps: Locate the adjustment straps on the back panel of the backpack, typically near the shoulder straps. Loosen these straps to allow the harness to move freely.
- Slide Harness to Match Torso: Adjust the harness up or down until the shoulder strap attachment point aligns with your measured torso length. The top of the hip belt should rest comfortably on your iliac crest.
- Secure Adjustment Straps: Once the desired position is found, tighten the adjustment straps to lock the harness in place. Ensure it is securely fastened to prevent shifting during use.

The removable GearUp PRO XL camera insert provides dedicated protection for your camera gear and can be configured to suit various setups.
- Access Main Compartment: Open the main access points of the backpack (front or rear).
- Position Insert: Place the GearUp PRO XL insert into the designated lower compartment of the backpack. Ensure it sits snugly.
- Secure Insert: The insert may have internal attachment points or straps to secure it within the backpack, preventing movement. Fasten these if present.

3. Utilizing Accessory Straps
The backpack includes a system of accessory straps for modular equipment transport, allowing you to attach additional items externally or carry smaller cases.
- External Attachment: Use the various external loops and compression straps to secure items like trekking poles, tripods, or sleeping pads.
- GearUp Case Integration: The accessory strap system is designed to integrate with other Lowepro GearUp cases, allowing you to attach them to the shoulder straps or hip belt for quick access to smaller items like phones or extra lenses.

2. Packing Essentials
Beyond camera gear, the backpack is designed to accommodate multi-day excursion necessities.
- Upper Compartment: Utilize the spacious upper compartment for soft goods like sleeping bags, tents, and extra clothing. The roll-top closure allows for flexible capacity.
- Side Pockets: Integrated side pockets are suitable for water bottles or quick-access items.
- Hydration Sleeve: A dedicated sleeve is available for a hydration reservoir (not included), with a port for the drinking tube.
- Accessory Pockets: Smaller pockets on the hip belt or lid can store snacks, maps, or other small personal items.
3. Using the All Weather AW Cover
The integrated All Weather AW Cover provides protection for your gear in adverse conditions.
- Deployment: Locate the AW Cover, typically stored in a dedicated pocket at the bottom of the backpack.
- Coverage: Pull the cover over the entire backpack, ensuring all exposed areas are protected from rain, snow, or dust.
- Securing: Fasten any elastic bands or drawstrings to keep the cover snug against the backpack, preventing it from being blown off by wind.
Maintenance
Proper care extends the life of your Lowepro PhotoSport PRO BP 55L backpack.
- Cleaning: For general cleaning, wipe the exterior with a damp cloth and mild soap. Avoid harsh detergents or solvents. For stubborn dirt, use a soft brush.
- Drying: Always allow the backpack to air dry completely before storing, especially after exposure to moisture. Do not use direct heat sources.
- Zipper Care: Periodically clean zippers with a small brush to remove dirt and debris. Lubricate with a silicone-based zipper lubricant if they become stiff.
- Storage: Store the backpack in a cool, dry place away from direct sunlight when not in use.
- AW Cover Care: Clean the All Weather AW Cover separately if needed and ensure it is completely dry before folding and storing it back in its pocket.
Troubleshooting
Here are solutions to common issues you might encounter:
- Discomfort or Uneven Weight Distribution:
- Ensure the ActivLift harness is correctly adjusted to your torso length.
- Verify that the hip belt is snug and resting on your iliac crest, bearing most of the weight.
- Check that shoulder straps are tightened enough to keep the pack close to your back but not so tight as to lift the hip belt.
- Distribute contents evenly within the backpack, placing heavier items closer to your back and centered.
- Zippers Sticking:
- Clean any dirt or debris from the zipper teeth using a small brush.
- Apply a silicone-based zipper lubricant to the teeth.
- Water Leakage (despite AW Cover):
- Ensure the AW Cover is fully deployed and securely fastened around the entire backpack.
- Check for any tears or damage to the AW Cover. If damaged, it may need replacement.
- Inspect the backpack's fabric for any punctures or compromised seams.
