The Echo composite seat mixes style and comfort, with racing functionality. The seat is built with off-road in mind, with thick dual-density foam all around, and built in lumbar support for added comfort. The large harness slots on the back allow you to fit the harness, and a fresh air hose through at the same time. Wrap around head containment prevents the drivers head from jarring side to side on impact. The Echo is slightly shorter than our Alpha Composite seats, allowing it to fit into smaller interiors (such as Trophy Lite trucks). FIA 8855-1999 Rated for Racing Applications.
