The Profi II ASM FE incorporates Schroth's legendary ASM (Anti-SubMarining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt.
