Roughly, how much sand would fill the base?

I filled mine with water. Using sand, I would expect to need 2 5-gallon buckets to get the weight up to 100lbs.

El producto es bueno, y ya. Creo que le falta calidad para acercarse a ser un cobra bag de los mejores. Entonces, por el precio creo que se debería mejorar un poco más la calidad!
