RE: scent lock or scent block clothes
good luck Stubblejumper!
For me hogs have one of the best noses ever. And the ONLY times I've ever seen them approach a stand from downwind and continue on to where I could shoot another one with my bow has been with scentlock type suits on. With prices around 100 bucks or just over its cheap insurance as an outer layer.
And we tried a test inside a ground blind (cloth) where a guy on an exotic hunt had animals downwind a bunch. He would take the hood off and the top off quietly and the animals would smell him shortly thereafter. This was in warmer temps FWIW. And being in a pop up blind they could nto see or hear his mimimal movement. I should add these were wild free ranging animals, not penned up and fed like cattle.
Best of luck, Jeff
