Drastically reduce the time it takes to remove water puddles from your field. Constructed from heavy-duty filtering fabric, the pillow allows water to flow through, but not the dirt. Can be used time and time again. Simply place in standing water, when saturated, remove and squeeze dry. Pillows are seamed in the middle creating 2 pockets which allow the pillows to be hung over the fence to dry. 10 pillows per case, each pillow can absorb up to 3.5 liters of water.
