Read and understand the directions.

Ionce took a test were in the directions it said I would not be penalized for a wrong answer. No one that I knew of heard what was said, save me.

The directions say that washing is the killer of the garment. I've washed mine once in 2 years. The directions say to only wash them when they are visibly dirty, mine had some blood on them because I was to tired to pack them out as I always do after a successful hunt. I keep the stuff clean by only wearing it while hunting (understand what I just said). Wore mine all season and hadn't washed them since the year before. I still have only washed the pants and don't think they'll need washing untill next season, if then. Not once did I get busted. Try doing that with any other hunting clothes. The directions claim they will loose their effectiveness after 20 washings.

Just read and understand the directions.
