Secure Rear-Panel Camera Access

The BackLight 18L opens from the side resting against your back. This design helps protect zippers and camera equipment while you are wearing the backpack.

When working in wet, muddy, sandy, or crowded environments, you can rotate the bag around your waist and access the camera compartment without placing it on the ground.

Flexible Camera Storage

The customizable camera compartment can accommodate:

• Two standard-size camera bodies with lenses attached

• One to three additional standard zoom lenses

• Flash units and small accessories

• A large telephoto lens, depending on configuration

Possible configurations include select 300mm f/2.8 or 150–600mm lenses attached to a compatible camera body. Capacity will vary according to the exact equipment and divider arrangement.

Adjustable padded dividers allow the interior to be configured for DSLR or mirrorless camera systems.

Separate Personal-Gear Compartment

A dedicated 5-liter front compartment provides space for personal items such as:

• Lightweight jacket

• Snacks

• Maps or guidebooks

• Sunglasses

• Headlamp

• Travel accessories

• Small outdoor essentials

This separation keeps personal belongings away from delicate camera equipment.

Laptop and Tablet Storage

Dedicated padded compartments hold a laptop up to approximately 13 inches and a tablet up to approximately 10 inches.

This makes the BackLight 18L suitable for travel, location editing, tethered shooting, and photographers who need to carry a compact mobile workstation.

Comfortable for Travel and Hiking

The padded shoulder harness, adjustable sternum strap, supportive waist belt, lumbar padding, and ventilated air channel help distribute weight during long walks and outdoor assignments.

The waist belt transfers some of the load away from the shoulders while also supporting the backpack during rear-panel access.

Flexible Tripod Carrying Options

A tripod or monopod can be attached to either the front or side of the backpack. This allows photographers to balance the load or keep one side pocket available for a water bottle.

Two large stretch side pockets can accommodate accessories or bottles as large as a 32-ounce Nalgene-style bottle.

Durable, Weather-Resistant Construction

The BackLight 18L is made with durable, water-resistant coated nylon and dependable YKK RC Fuse zippers for regular travel and outdoor use.

An included seam-sealed rain cover provides additional protection during heavier rain, dusty conditions, or unexpected weather.

Ideal For

• Travel photographers

• Hiking and outdoor photography

• Wildlife and nature photography

• Landscape photographers

• Mirrorless and DSLR camera systems

• Photographers carrying a compact telephoto kit

• Airline and road-trip travel

• Day hikes and location assignments

• Photographers who prefer rear-access security

• Anyone needing camera and personal storage in one compact pack

How It Compares

Compared with the Think Tank BackLight 26L

The BackLight 18L is smaller, lighter, and easier to carry for day trips or compact camera systems. The 26L provides additional space for larger professional equipment, more lenses, and extra personal gear.

Compared with the Lowepro Flipside BP 400 AW III

Both backpacks offer secure rear access and outdoor-oriented construction. The Think Tank emphasizes a streamlined hiking-style harness, flexible tripod placement, and separate storage for both a laptop and tablet.

Compared with a Front-Opening Camera Backpack

A front-opening backpack generally needs to be removed and placed on the ground for full equipment access. The BackLight 18L can remain supported by its waist belt while the rear camera compartment is opened.

Compared with a Shoulder Bag

A shoulder bag may provide faster access to a small kit, but the BackLight distributes weight more comfortably across both shoulders and the waist—especially useful when carrying equipment for extended periods.
