The Saddle Starter Kit includes the Mantis saddle, Tether, Lineman belt, and optional platform. This is everything you need to get hunting. The Predator platform is not essential if you already have some sort of platform to rest your feet on at hunting height. This could be a ring of strap on steps, screw in steps, or DIY solution.
Some optional accessories include SYS Haulers for storing gear on your Mantis, the Mantis Recliner back support band for long-term comfort, and the SBW Heater for those late season hunts when you need extra insulation. Accessories can be added to your order a-la-cart.
