Using the right waterproofing product is important to any sort of gear. NIKWAX TX.Direct Spray is fantastic for raingear with wicking linings, as it provides DWR without impairing wicking properties. Your gear could be inhibited from performing well because it is dirty. After a while, dirt and oil particles start to build up over the DWR coating and blocks it from holding off the water. Cleaning your gear with Tech Wash then spraying TX.Direct Spray On (no need to dry between) will restore those particles and make your jacket as good as new!
This spray is built for gear such as bivy sacks, synthetic sleeping bags or garments with knitted, wicking linings. It also works for clothing but we recommend TX.Direct Wash-In for most jackets and garments.
