There is no exact answer to this, because the durability of a pair of Archies Thongs depends on many different factors, such as frequency of use, type of use, the surface that they are commonly worn on, product care and so on.
However, generally speaking, the thongs are exceptionally strong and will almost always wear out before they break! This is something that our customers frequently tell us and it is extremely rare for us to ever get any customer complaints about the durability of the thongs.
We have witnessed people wear the same pair of Archies Thongs for over 5 years, however, normally, the grip will be well worn down after wearing them for this long.
Our general advice, is that with proper care, you should get one to two summers of excellent use. After the first year the lifespan depends on the factors previously discussed.
Also, everyone has a different definition of what's worn out and what's not! While we believe that the wear of Archies Thongs is excellent and as good as you will ever find in this sort of thong, at the end of the day they still are just thongs (very special thongs thongs!) and after considerable use they will eventually start to wear down and out.
Our warranty covers the thongs for up to 6 months from receipt of the goods. For more information please see our Returns & Warranty section of this website.
