Fill it your self
Sandbags are used whenever you need extra weight to prevent tipping. You usually "bag" stands, especially when the weight is off center, such as with a heavy Scrim. Matthews employs an additional inner liner of waterproof material in each sandbag to add a heightened degree of durability and safety. Matthews sandbags preserve their ability to mold themselves around any object, thus extending the life of the sandbag. The outer shell of the Matthews sandbag comes in two different types of material: a heavy-duty cordura or vinyl fabric. The cordura is made out of flame resistant and stain resistant nylon. It has a tensile grab of 500lbs warp and 400lbs fill, a tongue tear of 40lbs warp and 30lbs fill, and a fabric construction of 35lbs warp and 24lbs fill. It is coated in solvent urethane with a plain weave and a dyed finish (the color of your choosing). Essentially, you are getting the most quality product manufactured anywhere at an affordable price. The vinyl Matthews uses is a polyester woven fabric that is mildew and ultra violet resistant, meaning the fabric will resist mildew build-up and fading color in the sun. This material is also manufacturer guaranteed against rips
