Our regular size car trash bag made with a light gray regular weight fabric on the exterior and solid heavyweight gray canvas on the interior. The strap is made with 1-inch wide nylon webbing and secured with a plastic side release buckle. I have found this feature makes emptying the bag a whole lot easier. I use the time while refueling to empty mine! With the strap being easily adjustable you have the ability to hang your bag just about anywhere. Around a headrest, over a gear shift, in the back seat, etc. Large opening (at least 19" in circumference) 8.5" in height 6" x 4" rectangular bottom 15" Adjustable nylon webbing strap 2+" non-adjustable nylon webbing strap Machine washable **All measurements are approximate. Disclaimer: Do not hang any bag where it may impair your vision or ability to control your vehicle safely!
