Sandbags by Matthews are heavy duty cordura or vinyl bags filled with sand. That's the simple explanation. The complex explanation details the type of sand and other materials Matthews uses to make its sandbags the toughest and most reliable sandbags in the industry. Different types of sandbags may be purchased with alterations to the original design suited to fit your needs. Those needscan be anything from weighting down a stand or part of the wing of an airplane to doing exercises that call for weight to be used ineither a gym/body-building type atmosphere or a yoga class. There is absolutely no need for you to search any longer - we have the sandbag that is right for you.
First, the sand. Taken deep from the Malibu beaches, drawn from that stretch of sand that houses the dead bodies of the Baywatch cast and crew, Matthews sand is of the highest quality. This sand is commonly known as silica sand; it is a purified type of sand engineered to resist odors and staining due to exposure to water or other types of liquids. Practically speaking, this will ensure that if you should happen to get the sand inside the bag wet, you are spared the nasty smell that inevitably accompanies wet sand drying in an enclosed space. Whew! However, it should be noted that with a Matthews sandbag it is very difficult to actually get thesand inside the bag wet. Why, you ask? Well, Matthews employs an additional inner liner of waterproof material in each sandbag to add a heightened degree of durability and safety. This is especially important in conditions of extreme cold as the inner liner helps to prevent the sand from getting wet, thus preventing the sandbag from freezing and losing it's malleability. Matthews sandbags preserve their ability to mold themselves around any object, thus extending the life of the sandbag.
Now, 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 and tears.
