Bestop has redrawn the boundaries of soft top design again Trek top NX Glide combines fold-back convertibility with today's most desirable slant-back styling and even better, zippered side and rear windows. Like All Trek top soft tops, it also features our patented sunrider flip-back panel above the seats. The result is a whole new level of soft top functionality and enjoyment. Innovative new folding frame design (patent pending) lets the Trek top NX Glide operate like a Convertible top - just fold back behind the rear seat for a total open-air ride. For full coverage, the Trek top NX Glide is fast and simple to put back in place, just like our Super top NX. Available in our best Black Twill acrylic 30-oz. Fabric or factory-standard black diamond 28-oz fabric.
