Here are the sites I told you about.
Jacket: http://thru-hiker.com/materials/index.php If you are ambitious try the Maxima Jacket. The Multicam jacket I was wearing is a version of this pattern. The vest was my design.
Tyvek: Apparently the Tyvek site I bought my ground cloth from doesn't exist anymore. It was http://www.materialconcepts.com. It was a great site; they offered lots of different grades from soft, sew-able to heavy ground cloths.
Does anyone on the forum have a site for buying Tyvek other than e-bay?
