Kydex is a strong material, but it will crack or break over time. As with any material that is used, Kydex is a material that will wear and break at some point and more quickly if it is repeatedly flexed. Any product you will use, regardless of the material it is made from, will wear out sooner or later. Even an item as sturdy as a Kydex gun holster will eventually break, especially if worn every day for work. Based on customers’ experiences, holsters made from 0.08 inches Kydex sheets are more durable than those made from 0.06 inches sheets. If the holster is used every day, the daily wear and tear will eventually make it weak, no matter how strong the material is. To make the most out of your Kydex sheath, use the right sheet thickness. Users recommend 0.08 inches or 0.093 inches over the 0.06 inches thick; otherwise, you will need to replace your Kydex holster after a year or two if you use it on a daily basis. Kydex holsters made from 0.06 inches thick sheets may last a long time, even a lifetime, if the user does not have a very active lifestyle. If you carry your gun holster around every day, it will weaken from the different elements you put it through.
