That's it....I got mine from Realtree's website, but to be honest, it's not very good. I didn't even get one season out of it before it fell apart. I would just use an old sock. Cut the foot out of it and sew the end of it to keep it from unraveling.

OR, you could use an armguard. Realtree's is a neat idea, but it just didn't hold up very well.
