Rear panels are optional and can be added or removed. Every GRILLKILT ships with 3 panels included. If your waist is larger than 46", and you would like FULL rear coverage, we recommend purchasing a pair of extra rear panels.   Each additional rear panel adds an extra 8" of rear coverage, so about 16" per pair.  Rear panels are sold in matching colors (we will ship the same color as your GRILLKILT order).  One pair will be enough to cover the entire belt, so you only may need to order one extra set! 60" is the maximum waist that the original GRILLKILT can accommodate at this time.  If you need a larger belt, please email us for a custom order.
