Kitespar is a fiberglass tube that has an extremely high strength-to-weight ratio. .602 (sometimes erroneously called 'six ten') Kitespar has a weight of 2.9 grams per linear inch and is recommended for down spears, short poles, or weapons up to five feet in length. .602 has wall thickness that is comparable to .524 but on a larger diameter, meaning that it effectively flexes less and is stiffer, but is not necessarily any stronger. Because it flexes less, .602 kitespar is more effective at delivering force on impact.
This piece of .602 comes in 60" lengths.
