Butted 16g 5/16" saw cut bright aluminum rings were used to create this 4.3" wide lightweight harness. Harness is made from two loops of European 4/1. Length ordered is the total length of the loops, NOT each side so for example the 50" would be two 25" sides. Total weight is also dependent on length but should be between 7 - 10 ounces (2 - 300 grams).
