The black Glass Limo Backpack from ThinkTank is specially designed to hold long lenses. Specifically, it's meant to accommodate a 600mm f/4 or 500mm f/4 without a body attached or 400mm f/2.8 with pro body attached. The backpack has a padded collar for stabilizing 300 mm and similar size lenses. However, when fitting larger lenses, you must remove the padded collar, or the larger lenses won't fit properly. A versatile backpack, it can be reconfigured to hold a standard DSLR and about 5-8 lenses. The interior movable touch fastened dividers allow you to customize the pack to suit your gear needs. In order to hold the long lenses in place, the pack comes with specially designed touch fastened collars that secure the lenses in place.

For storage, there is a zippered front organizer pocket for pens, drive, note pad and other small items. Your tripod or monopod can be attached to either side of the pack using the included straps. And, because ThinkTank knows that a day in the field can be rough, water bottle pockets are included on both sides of the pack.

The Glass Limo is carried by its adjustable harness or top carry handle. A waist belt is also included for balance and stability. The Glass Limo accepts ThinkTank's optional Pro Speed Belt or up to three optional modular pouches. A rain cover is included for inclement weather.

The pack is made from a combination of durable water repellent fabric, polyurethane, nylon and ripstop polyester. The interior is a polyethylene board with removable closed-cell velex foam and nylon. The zippers are all YKK with pull tabs and designed to stay closed so your gear won't slip out. ThinkTank warrants the Glass Limo Backpack against manufacturer's defects.
