An evolution of the Stallion 500, the STX Stallion 600 Lacrosse Helmet features an improved fit, design and protection system. This helmet is recommended for anyone over the age of 13. By teaming up with Schutt, STX has designed a superior helmet with Hybrid TPU cushioning and a polycarbonate shell that is stronger and more comfortable. The patent pending D30 padding material features a unique molecular design that remains soft in its natural state but hardens upon impact to absorb and disperse impact energy. The Stallion 600 also now features TPU side pads as well as additional EVA padding for a superior feel. The Surefit Air Liner includes a pump so you can inflate your helmet to fit the contours of your head perfectly.
