Kodiak provides a lifetime warranty on their tents. The warranty obviously doesn't include negligence such as rolling it up when it is soaking wet (happens more often than you'd think). They are that confident in the longevity of the Kodiak flex-bow tents that they provide such a long warranty. Warranty calls are quite rare. When they do get warranty claims they are quick to honor them whether it be sending a new part or sending a new tent if needed.
My personal Kodiak tent has lasted over four years with about 10-15 days of use per year. I haven't had a single issue and have had many boy scout troops, churches, and neighboring campers ask where I got such a hardcore tent.
