The in-mold-constructed Symbol 2 Plus D employs Scott’s proprietary safety technology, D30. The D30 shock-absorbing inserts utilize a material whose molecules flow freely in open cells—which translates to softness and flexibility—during its resting state. But, when it sustains an impact, the molecules lock together and distribute force across the material and thereby away from the user’s brain. The use of MIPS, in addition, makes the Symbol 2 Plus D a trusted guard against brain trauma.
