The lifespan of a tent can vary widely depending on how often and in what conditions it is used. Exposure to UV radiation from the sun is one of the main factors that can cause a tent to degrade and break down over time. A tent that is frequently used in extreme conditions, such as high altitudes or harsh weather, may only last a few months or a year or two. On the other hand, a well-maintained tent that is used occasionally under normal conditions can last for many years.
