I would tend to agree with Bearbuster. Scentlock has been doing just scentblocking suits for close to 15 years, while robinson labs has had their hands in different anti scent products. I truly believe that if you take the proper steps in maintaining your suit, use all the soaps and shampoos, use carbon spray, and get high enough in a tree you can be nearly oderless. Also i would have to say that a scentlock head cover and gloves would be the two most important pieces of a scentlock suit.
