Re-waterproofing your tent is a crucial maintenance that helps extend the lifespan of your gear. If you've noticed that the water repellency of your tent decreased or water is seeping through, it is time to reapply a waterproofing treatment. One product we highly recommend is Nikwax SolarWash.
The frequency of re-waterproofing depends on how often you use your tent and the conditions it faces. As a general rule, consider reapplying a waterproofing treatment after every season.
