I spent three seasons, from four to five and a half months alone on AFS towers, two on Athabaska out of Hinton and one on Doucette out of Wabasca. I spent four seasons on four BC Lookouts in different regions of BC and, believe me, there were LOTS of bugs on all of these!

I used headnets and now use The Original Bug Shirt, the best rig I have found in the 59 years I have been carrying packs in the mountains. These are made in Ontario, I worked on a tree farm there and they have bugs by the freakin bazillions, they can be had in camo and would be ideal for sheepists in early season.
