5-Pound Parachute Rigger Shotbag.
This 5-Pound Shotbag is a must for packing reserves. Made of 2" red tubular nylon webbing and lead shot.
ChutingStar riggers usually use 3 of these for holding the initial square canopy folds in place and keeping the air out before placing the canopy into the freebag. For round canopies, riggers use 6-10.
