I'll be heading on my first Dall sheep hunt in the Yukon this July so the bugs will be bad. Looking for recommendations for treating the merino wool shirts to prevent getting bit by these freaking critters. Looking at treating with Sawyer Permethrin clothing treatment but not sure if this is a good idea with the wool. Any other recommendations, treat with OFF or a product with DEET??

Any other suggestions for keeping the bugs off and not feeling greasy or smelling too bad would be greatly appreciated. Thanks
