Phottix Stay-Put Sandbag II (Medium)

Filled it with 13 pounds of sand from the driveway and it’s completely changed how secure my light stands feel, even in a stiff breeze. The carry handle and sturdy fabric make hauling it out to the field pretty painless, and the empty design means it’s not a pain to store between shoots.

Started using it on a windy beach shoot and my light stands didn't budge at all, even with the 13.2 lb sand capacity filled. The double-stitched seams feel solid, and the built-in handle makes carrying it a breeze.

Filled mine with pea gravel from the garden center and the 13.2 lb capacity keeps my softbox rock steady, even in a light breeze. The handles are well-placed for carrying it when it's full.
