The early versions of the venerable 60/40 mountain parka from Sierra Designs was similar. The outer was 60/40 cloth (60 percent cotton, 40 nylon) but the inner layer was ventile cotton through the arms and down to the waist. It worked on a similar principle. The outer layer could wet through but not the ventile. ralph -- ----------------------------------------------------------------------- Ralph Diaz . . .
