The Spyne series of heads use a high performance super stiff, proprietary polymer blend called "TEK9".
This state of the art, high performance blend is more resistant to heat and less likely to breakdown and become soft while you are playing. They are 25% stiffer than normal heads.
Official Spyne jewel logo molded directly into the throat shows your head is ultra stiff and puts regular lacrosse heads to shame.
All Spyne series heads come with a 6 month, limited warranty, against manufacturing defects.
