8 Seasons with Smarty, still waterproof
I bought a pair of these back in 2003 and they are still in great shape despite the abuse I have given them. I wash them with Nikwax after each season, but it doesn't really need it. The zip out line is great. I have used these pants on zero degree days as well as 60 degree days and they handle both great even without long johns. These pants may run a little bit large, but have great mobility.
