Giottos Normal Tripod Sandbags are a great way to add an extra counter-weight to your tripod. Most tripods aren't heavy enough on their own to the withstand the extra strain of heavy lighting systems, bulky cameras, or expensive accessories without toppling over. Giottos knows that serious professional photographers need a counterweight to balance all the equipment they require their tripods to carry, which is why they developed these great tripod accessories. Constructed from durable, high grade 1680d nylon double jacquard fabric, the Giottos Sandbag Tripod Counterweight won't burst or tear, even when it's filled to the brim with sand. The covers of the Giottos tripod accessory are twice-coated for excellent waterproofing. The internal frame and handle attachment of the tripod accessory make it easy to carry and even easier to fill and empty. And it's possible to add even MORE weight to your tripod with the hidden cord of the sandbag, which can be tied to the center column of your Giottos tripod and used to connect extra sand bags. For a clever and versatile tripod counter weight, tie down a Giottos Normal Tripod Sand Bag.
