Just heavy duty enough to not allow stakes to poke out but only 1/2 ounce. The Tarp Stake Bag will hold well over a dozen tarp stakes if you need it to and keeps them secure from grabbing onto your other gear. Pick from 8" or 10" and choose from 5 colors. Made from high quality 250D Diamond Ripstop fabric the Tarp Stake Bag will hold up against years of use.
