Like any other piece of horse equipment if you look after it correctly it can last a long time. Horse equipment is designed to stand up to equestrian life, but cleaning your tack will make your investment last longer.
We suggest cleaning the leather on your girth with saddle soap and oil as needed. The elastic can be cleaned with a wet or dry dandy brush and a non-chemical shampoo/soap and air dry.
Just wipe the neoprene gently with a damp cloth. Although it is solidly adhered to the leather it won't take rough treatment and is not covered under any warranty.
