so im at the texas state parks and wildlife expo in austin last weekend and i run up on this fellah selling shirts and sleeping bags made of "eliotex". he claims it has incredible insulation capabilities. i took his card and looked it up. looks like postal packing material to me but who knows? does anyone have any clue about this stuff? i dont work for them or anything...didnt even buy anything from them. but if its got potential......
