As you guys know I kayak a lot and been using dry bags (roll down) or if I know that water is pretty calm I jsut strap my bag to the top of the deck and just make sure that radio/camera/lighter is in the ziplock. My packing list for kayaking has been the same for ages and it doesn't take much space.

I want to buy a waterproof duffel bag (medium sized) for both kayaking (strap to the deck) and travel (just carry on or camera gear protector). I would like it to be yellow or red. Size wise it has to hold a fleece, rain jacket/pants, tshirt, swim shorts, 2 pairs of socks, small fleece liner, radio, camera, few lightsticks, small pouch with odds/ends and FAK. Reason I don't want to use roll down bags is that they are difficult to get into and can only be used on water and I would like to use the duffel for travel as well.

I was looking at these but don't know how waterproof they are:

Any ideas?
