Originally, stone bags were designed to provide a counterweight for additional stability when working with a tripod. Today, however, the usage of stone bags has been extended to providing a supplementary place for artists to store supplies while working in the field, making the SoHo Stone Bag an ideal accessory for both plein-air Painters and photographers. This bag comes empty, but can be filled with various Weighted objects, such as sand or gravel, to provide stability when painting in windy outdoor conditions. Photographers can also use it as a counterweight when working with a heavy camera or lens combination. Working with a tripod field easel does not give you a lot of area to lay out supplies when working. Having a stone bag attached to your tripod allows you to store and access additional supplies you may need with ease. From palettes to extra camera lenses, this bag is large enough to accommodate most materials you would bring into the field with you. This bag measures 14" across and has a depth of 7-9.5" and will allow any load up to 35lbs. Ingeniously designed, the extended length of the adjustable strap to the leg is 6.5", and the ties are 7", so it is easy to take on and off. The durable bag is made of a PVC-coated polyester Material, which is easy to clean and folds up easily, which adds very little Weight to the supplies you carry into the field.
