Gitzo Tripod Bag Systematic Series For 2, 3, 4, 5 or Tripod Plus Large Head. Our tripod bags have been redesigned to fit the latest Gitzo tripod models & more tripod & head combinations, & to improve comfort during carriage & handling. The new bags are made from rip-stop fabric, which is both softer to the touch & resistant against tearing & abrasion. GC4101 has an asymmetric form with more space at one end in order to accommodate larger heads. It fits all stand alone Systematic Tripods, & some combinations with heads. The shoulder strap is fixed to the bag for maximum stability.
