Size-adjustable 100% waterproof storage for your hitch rack! The Rightline Gear Hitch Rack Dry Bags keep gear dry, no matter the shape or size. A step up from rectangular hitch rack bags that can't hold large odd-shaped gear and tie-downs that can't keep gear dry. Heavy duty straps secure the bags in place. After use, the bags fold down into a small stuff sack that can be stored behind or beneath the vehicle's seats. The Hitch Rack Dry Bags also work great in truck beds.
