The Easton Stealth is a newer head from a new company to lacrosse, Easton. It features a few unique elements such as its adjustable offset and pinch system. By adjusting a screw in the throat the offset and pinch can be adjusted. This head is NHFS spec and is legal for all levels of play excluding NCAA. I recommend this head for attack or midfield as it is an offensively oriented head.
