This Hoop Boat Trash bag has a Nylon and Mesh Bag measuring 10" wide by 27" deep. Plenty of space for trash. It can hold up to 3 gallons (680 cu-in) of garbage. The mesh allows it to breath and the materials are easy to clean. You can line it with a kitchen bag if you prefer. The hoop opening measures 4-1/2" inside diameter and is big enough for most bottles and cans. The bag is removable if necessary. Tie-downs are made of parachute cord and polyethylene clips at the top and bottom to secure the bag to a post, t-top, rocket launcher, etc.
