I didn't actually expect to get to test out the waterproof qualities of this cargo bag so quickly, but the first time we used it (on a week long camping trip to Dinosaur National Monument) it poured rain all the way to the campsite and for the first day and a half.  It kept everything dry and secure without a problem.  Other than dealing with the extra lengths of nylon strap when it's cinched down, I didn't find any flaws with the product.  Great capacity and it's nice to only take up the space you need compared to a cargo box.
