I just got back a month ago from hiking with Shewie and some of the other BC hangers around Braemar (Scotland Highlands). I had a stock BB bug net and I was midge free. I did have a top cover but it is not form fitted and it was not what was keeping them out. I heard about how they can get through the net but it held them at bay. BTW take a head net, gloves, and avon's skin so soft.
