Seattle Sports Aquaknot 1800 Waterproof Backpack - The Aquaknot 1800 waterproof backpack by Seattle Sports features a comfortable back panel with an air-flow design, gusseted side exterior storage pockets, super reflective patches, an outer storage bungee net, and a versatile 3-way closure system. This unique 3-way closure system is designed to meet the various needs and desires of different users:

1) For the kayakers and rafters liking side closure, the detachable straps can cinch down to the sides of the bag, connecting to traditional top buckles (that are otherwise hidden in a clever buckle garage).

2) For the cyclists and others wanting a quick clean closure but don't need cinch down waterproof protection, the side straps clip off and the buckles hide to allow for a simple center-mounted over-the-top Velcro style strap to keep the bag closed

3) For the dry bag purists wanting a traditional clip-together closure, simply expose the top quick release buckles, roll three times and clip together in the center.

    This bag arrived on time and in good shape. It's bigger than you would think. Considering that its a waterproof bag, the opening of it does not have a waterproof seal. I don't need a totally waterproof bag, but be warned. The bag looks nice and its comfortable.

    This waterproof backpack came in really handy when we recently went to Universal Studios in L.A. Our extra clothes, small towel and cameras were all well protected when we rode the Jurassic Park ride. I hope you enjoy this product as much as I did.
