Our yellow poly tarps are perfect for protecting your things outside. They are made of very strong 1200 denier fiber and have a 14×14 mesh count per square inch. This makes them super durable and able to withstand all types of weather. The tarps are also waterproof and protect against the sun’s harmful UV rays. They have grommets, or metal rings, spaced 18 inches apart on all sides, making it easy to tie them down. The finished size of the tarps is 6 inches or just a little smaller than stated, and they are about 10-12 mils thick. Please note that the color may vary slightly.
