Sometimes I wear it and sometimes I don't. The suit I have is not for early season so I wear it only in cooler temps. I'll probably end up getting one of the suits for warmer weather. I've hunted plenty without it so I've NEVER considered it a necessity, only a preference based on my experiences with it in the field. I also have the silver impregnated stuff top and bottom that I wore early this past season. I didn't seem to have much luck with that, having been busted a few times. But I'm still going to wear it and see how it goes. I don't wash my scentlok stuff much, once or twice a season. I try to keep it in a scent bag and not sweat in it when wearing. I think sweat is the major contamination that will ruin the suit. I also have gloves and, to me, the most important piece is the scentlok face mask. The facemask will obviously lose its effectiveness the quickest followed by the gloves. I like to chew Copenhagen when I'm hunting and my experiences (not using scent clothing) have been that I got busted less when I didn't chew. I've found using the scent face mask I'm able to chew and still have deer in my face. Even in warmer weather when I'm not wearing the suit I still wear the mask. I've got a Scentlok Leafy 3D suit, a couple of scentlok gloves, and Scentlok half mask and Scentlok 3D full head cover mask. I normally wear the full head cover, which had a very small brim (almost none). I've found the deer seem to be able to pick out my eyes when wearing the full head cover. Haven't had any bolt but have had some look around and get that surprised look once they spot my eye area, usually end up walking away. I have always worn the camo bucket hats and found if I put it on over the head mask it provides enough shade that they don't pick out my eyes.
