🔒 Secure Rear Camera Access

The primary camera compartment opens from the back of the backpack. When the bag is being worn, the main zipper rests against the photographer’s back, making the equipment compartment difficult for another person to access.

Rear opening also keeps the shoulder straps and back panel away from wet, dusty, or muddy ground. Simply remove the pack, place its reinforced front against the ground, and open the rear panel for complete access to the equipment inside.

This design is especially useful for:

• Travel and sightseeing

• Crowded events and public areas

• Hiking and outdoor photography

• Urban and street photography

• Wildlife excursions

• Photographers carrying valuable equipment

⚡ Convenient Side Access

A separate side-access opening allows the photographer to retrieve a camera or change lenses without opening the entire rear compartment.

This provides a faster option when a shooting opportunity appears suddenly, while the full rear panel remains available for organizing or accessing the complete camera system.

📷 Flexible Professional Capacity

The spacious camera compartment can accommodate a professional DSLR or mirrorless camera with a portrait grip and an attached 70-200mm lens, along with approximately four to five additional lenses or flashes.

The adjustable padded dividers can be repositioned to fit:

• DSLR or mirrorless camera systems

• Large professional zoom lenses

• Multiple prime lenses

• Portable flashes and triggers

• Compact drones

• Small video equipment

• Mixed camera and personal-item configurations

The flexible interior allows the backpack to be adapted as equipment needs change.

💻 Laptop and Tablet Protection

Lowepro’s CradleFit compartment suspends and protects a laptop up to approximately 15". A separate compartment accommodates a tablet up to approximately 10".

The suspended design helps keep electronic devices away from the bottom of the backpack, providing additional protection when the bag is placed on the ground.

🛡️ Built for Outdoor Use

The Flipside BP 400 AW III uses rugged 600-denier polyester and ripstop fabrics with a protective front coating to resist moisture, abrasion, and everyday wear.

Molded EVA bumpers reinforce the front of the backpack and provide additional protection when the bag is placed on rough surfaces. Heavy-duty 10mm YKK zippers provide smooth, dependable access to the equipment compartments.

🌧️ All Weather AW Cover

The integrated All Weather AW Cover provides additional protection from:

• Rain

• Snow

• Dust

• Sand

• Windblown debris

When conditions improve, the cover stores conveniently inside the backpack so it remains available without requiring a separate pouch.

🎒 Comfortable Carrying System

The padded shoulder straps and supportive back panel help distribute the weight of a complete camera system during longer outings.

The backpack design keeps the equipment close to the body for improved balance while walking, hiking, or navigating crowded locations.

🧰 Organized Accessory Storage

A front storage panel provides space for cables, filters, notebooks, personal items, and other frequently used accessories.

The included removable padded accessory pouch helps organize smaller equipment such as:

• Batteries

• Memory cards

• Chargers

• Cables

• Remote controls

• Lens-cleaning supplies

• Small microphones or audio accessories

🦿 Compact Tripod Carrying

The exterior tripod attachment allows a compact travel tripod or similar support to be carried with the backpack.

This keeps the tripod readily available while preserving the interior compartment for cameras, lenses, and other sensitive equipment.

👤 Ideal For

• Professional and enthusiast photographers

• DSLR and mirrorless camera systems

• Travel and vacation photography

• Wildlife and nature photography

• Outdoor sports

• Hiking and landscape photography

• Wedding and event photography

• Urban and street photography

• Photographers carrying a 70-200mm lens

⚖️ How Does It Compare?

Compared with the Lowepro Flipside BP 300 AW III

The Flipside 300 AW III is smaller and lighter, with space for approximately three to four additional lenses and a laptop up to 13". The Flipside 400 AW III provides greater capacity, accommodates four to five additional lenses or flashes, and protects a laptop up to 15".

Choose the 400 AW III for a larger professional system or when carrying additional lenses, electronics, and accessories.

Compared with a Conventional Front-Opening Backpack

A conventional backpack provides quick access through its exterior-facing front panel, but its main zipper may remain exposed while the bag is being worn.

The Flipside’s rear-access design keeps the primary camera compartment against the photographer’s back, providing increased security while traveling or working in crowded areas.

Compared with the Lowepro ProTactic Series

ProTactic backpacks emphasize modular exterior attachment points and access from multiple sides. The Flipside offers a cleaner outdoor design with secure rear access, convenient side entry, and integrated weather protection.

Compared with a Shoulder Bag

A shoulder bag may provide faster access to smaller equipment kits, but it concentrates the load on one shoulder. The Flipside distributes the weight across both shoulders and is better suited to carrying a larger camera system over longer distances.
