How long your CamelBak lasts is ultimately decided by how well you take care of it! On average, a decently cared-for CamelBak can last you between 3-5 years. However, there have been some records of CamelBaks lasting up to 10 years with excellent care! If you tend to be rough and tough on your CamelBak with extreme sports, you may have to replace it every 1-2 years according to your needs. As long as there are no leaks or punctures, you're good to go!
