We tested this hitch carrier bag
on the back of a vehicle through a rainstorm, and put the bag through a garden hose spray test. On both occasions, the inside of the bag was totally dry. The hitch carrier bag will protect your stuff from the rain and road grime, wet or dry. The stitching is excellent and the anchor points are durable. The hitch bag comes with six straps and there is a strip Velcro to help seal the zip flap. The waterproof material is thick and good quality.
