This is super interesting— I have an obsessive streak and haven&#x27;t been thrilled about the seemingly slow progress in bringing new materials to use in the apparel market. I was actually looking into aerogel yesterday (it&#x27;s available as a commercial product now, from places like <a href="http:&#x2F;&#x2F;www.buyaerogel.com" rel="nofollow">http:&#x2F;&#x2F;www.buyaerogel.com</a>) and I was curious about why I hadn&#x27;t seen it in use for this application yet.<p>In general, I find it frustrating how difficult it can be to find materials to experiment with. I can get basic nylons from places like <a href="http:&#x2F;&#x2F;ripstopbytheroll.com" rel="nofollow">http:&#x2F;&#x2F;ripstopbytheroll.com</a>, but a lot of more interesting options (like the stuff by pertex) is really difficult to find by the yard.<p>&#x2F;derail
