The yellow, 20-liter Classic Waterproof Backpack from OverBoard is a bag with a 1,200-cubic-inch capacity that is able to float and keep its contents dry, even when briefly submersed to a depth of three feet. Utilizing a fold-seal closure that is secured with a snap-buckle, this bag features an IP66 rating and is suitable for use while on a boat, raft, or whenever there is an elevated risk of the wearer or their backpack falling into water. Aside from providing protection from accidental immersion and the ability for later retrieval, the Classic Waterproof Backpack may also be used for instances where some exposure to water is anticipated, such as while crossing a stream or river.

To help ensure that this Classic Waterproof Backpack is comfortable to carry, its shoulder straps feature both padding and ventilation in addition to a ventilated back panel that further cools the wearer. An adjustable sternum strap provides stability and built-in lumbar support reduces pressure on the lower back.

Should the need arise to retrieve this bag under darkness or low-light; reflective external patches are included on the front surface and on both shoulder straps. Three external D-rings allow for direct and secure attachment of accessories and an external mesh side pocket provides a visible and easily accessible compartment.

OverBoard OB1141 Reviews

5 Stars (I hope)!

I bought this to take my Z8 with a mid-size zoom onto a zodiac. I was worried whether there is ample room. I also bought both the Rugged 19x19 Equipment Wrap and the 3 Legged Thing Wraps (24") to help protect the gear while in and out of the boat. Although tight, I can get a second body and similar or smaller lens in the bag at the same time. I also considered the later Overboard backpack but am glad for my purposes I went with the 20 liter bag.

Works as expected

Took this to Antarctica to carry camera gear on wet Zodiac boat expeditions. Worked like a charm.

What is the interior like? Any pockets/ divisions? Any protection for camera gear?
Asked by: Kathy
The interior is just an open space. Consider it as a place to put your camera gadget bag, not as a camera bag itself.
