Revivex is the brand name that we carry and can be purchased from any Klim dealer or online. Most sporting goods stores carry some brand of spray on water repellent. Make sure the one you use states that you apply it on a wet garment and dry on medium heat.
What you're doing in this process is restoring the DWR (durable water repellency). Klim gear has small fibers that stick up off the fabric (you can't see these with the necked eye), these fibers repel water by causing it to bead up. If these fibers get matted down from being soiled, or from sitting on a seat, or pressure from backpack shoulder strap they won't cause water to beads like they are supposed to. If the water won't bead off it saturates your gear and you get what we call a "wet out" effect. The Gore-Tex is not leaking, but your gear feels heavy from the outer fabric soaking up water and you start to feel like your wet and clammy. This can create a couple of different conditions. It can slow down the breathability of the gear and can actually cause some people to develop condensation inside their gear which makes you believe its leaking water. For some body chemistries these conditions can be severe and for others they have little effect. The process we are talking about above restores the DWR fibers so that your gear will once again bead up and repel water. It's very easy to test your gear to see how well the DWR is working. Simply splash water on it and see if it beads up and rolls off or does it pool and soak in. Once we eliminate the possibility that you're dealing with a "wet out" condition we will bring your gear in and test it to see if its leaking water. It's guaranteed to keep you dry for the life of the gear. This confuses a lot of riders, but simply put we don't care if the gear is 10 years old or has 25K miles on it, if the gear is taken care of and not abused or destroyed we will repair or replace it. This is the main reason we ask you to wash your gear on a regular basis. Washing and drying will clean and lift the fibers on your gear restoring the DWR that causes water to bead up and roll off. All of our Gore-Tex products are designed and tested to allow you to wash them as often as you like yet allow you to remain confident the Gore-Tex will continue to do its job and keep you dry. Both the Gore-Tex laminate and the seam sealing is durable enough to handle the washing machine. Trust us
