The ranger green Sabi Sack from Gura Gear is a bean bag system that allows you to add stabilization where a tripod won't work. Its double-pillow design allows it to stand up on the ground or secure itself to things like car doors and tree limbs. It is supplied unfilled so that you can decide what best fits your needs.
This USA-made bag features Cordura fabric and reinforced handles for secure transport. Additionally, it features concealed zippers with a leak-stop tab to avoid spilling your fill.
