When should I discard my old climbing harness?

Manufacturers of climbing harnesses give different directions on how long their harnesses last before they should be discarded. Further, this may vary from harness type to harness type. In general, however, it can be said that nylon does not perish unless exposed to sunlight (ultra-violet light) or wet environments. Therefore, store your harness in a dark and dry place.

On all climbing harnesses the date of manufacture is given. A general guideline is that you should discard them after five years of use. However, whether the harness has been kept dark and dry for 10 years before does not matter. The five years are counted from the date the harness was put into service. However, we would like to point out that this is a general guideline and that the durability of all harnesses may vary from manufacturer to manufacturer and from harness type to harness type. Therefore, as a starting point, follow the manufacturer's instructions.
Ultimately, it is your responsibility that your harness is in good enough condition to use. Therefore, regularly check the harness for signs of wear and keep it in accordance with the instructions above.

Some climbing harnesses are made with a wear indicator. Ie an outer layer of durable nylon, over a red innermost layer of nylon which is resposible for the harness's strength. Gubbies recommend climbing harnesses with wear indicator.
