<DIV>It's interesting that DC first recommended mylar then switched to grill. These are two very different types of materials. They must have decided that breathablity was an issue. I thought maybe Gortex or some similar microporous material might be the best of both worlds. </DIV>

<DIV>Apparantly DC has done a lot of R & D over the years. I would be interested to see all the documentation on what tests they ran and what all the results were. </DIV>
