Unlike most of the US citizenry, our corporations do believe in global climate change and are looking for ways to adapt/profit. Bayer has come out with a polypropylene bugnet that supposedly maintains its insecticidal capabilities for up to 35 washings (five years).

Their market clearly isn't UL backpackers - they're trying to combat malaria. This is what they call a long-lasting insecticide-treated net (LLIN). Still, I wondered how this compares to noseeum (.91 oz per square yard) and nanoseeum (.70 oz per square yard). I'm assuming both are polyester (75 or 100 denier multifilament yarn), but maybe some of the heavier nets out there are polyethylene (100 to 200 denier monofilament yarn).
They say it's 40 g/m², which I translate as 1.4 oz/1.09 square yards. Their primary goal is durability, tear resistance and long-lasting bug protection through multiple washings. Sounds interesting!
