Most of the outdoor fabric sources have mosquito netting (OWF, The Rain Shed, Seattle Fabrics, etc.) Thru-hiker.com has extra lightweight netting.
I've never seen eVent for sale, but the other w/b fabrics work. RCT Fabrics sometimes gets overstock from the major manufacturers, so they might occasionally get eVent.
