STX X20 UNSTRUNG HEAD An all time favorite just got a makeover. The new X20 is an update on one of the most popular defensive heads of all time. The wide faceshape and tough exterior make this head perfect for the stay at home close defenseman, who loves to dish out punishment on opposing attackman. We also added Speed Scoop to the wider profile, making this head a menace on contested ground balls. Attackman, beware.
