Well, the Dek Nav by Pacific Outdoor was an expensive bag for me, as I had to import it into Holland.OK, not the end of the world, but, the mounting could include some sort of ring on EVERY corner of the bag as well, therefore, if the velcro straps let go, the rings, which could be used to further secure the bag to the Kayak, could hold the bag in it's place, provided that you have ADDED some extra hooks/cilps/rings to your kayak!!. The GPS compartiment is useless, as, there are NO GPS Systems that I know of, that has it,s screen readable in the HORIZONTAL position!! Most handhelds are only readable in the VERTICAL position!! For the rest I am still happy with my bag.

Although nothing got wet, on the whole I was disappointed with the bag. The description touted something along the lines of a "lateral mounting system" to securely attach the bag to the kayak. The system is three velcro straps on the bottom, which might have been strong, but the kayaks I used had nothing to strap them to, so I ended up putting it under the bungee straps on the kayak. I wouldn't have trusted the bungees to keep the bag in place if I'd capsized though.
The zippers were very difficult to use and after 5 days started separating from the bag.
The GPS window sort of worked, but glare off the window obscured the GPS screen a lot of the time. SInce my GPS is water resistant, clipping it to the bungee worked better, and kept it in a better orientation for reading.
I recommend not getting this bag.

Shoddy construction, the hook-and-loop closure was not properly sewn and quickly separated from the bag. Product returned and I will look elsewhere as the manufacturer was not helpful.

I just used this deck bag on a 5 day/4 night kayak camping trip to Lake Mead. When my boyfriend first saw the bag he made fun of it because it was so much bigger than his. He bought the "Sea Kayaker" Readers Choice "Seal Line Baja" deck.

By the time we had our gear ready he had more stuff spread all over his deck, while everything I needed including my CamelBak, was inside my one bag.

Also, the position of the paddle holder is closer to you than the Seal Line Baja Bag. I used my paddle holder all the time when stopped and my boyfriend always ended up trying to balance his across the cockpit.

I paid less than the Readers Choice Bag and it was roomier and easier to use!
