After about a year of almost daily use the original covering was wearing in certain spots, sort of smoothing out and becoming slippy, I recovered and used griptac from camera leather recently and love the feel. Very easy to apply and a must to use in the HOT HUMID hOustOn teXas. I purchased extra and covered the ZI side grip attachment for a bit of extra Grip, used another piece on the shoulder strap of my bag so it never slips off my shoulder again...
