# Mustang 18-21 Harley Softail Slim Tripper Fastback 1PC Seat - Black

The Tripper Fastback is low, lean and formed to feel as good as it looks. A low-cut 12" wide driver bucket combined with a rising tail section provides good back support for the operator, placing them lower and slightly further back than stock. The hand-sewn cover features Mustang's all-new "Double Helix" stitch pattern and contrasting mixture of black and carbon fiber-styled vinyl for a true custom appearance. The 6" wide passenger seating area features the Fastback's traditional sleek and streamlined profile while still offering a reasonable degree of comfort for 2-up riding.
