I've have X-Scent Base layer, (Cabela's has MTP Hunt Series Silk Weight stuff that is about $25 a piece), top and bottom, and it's good stuff. It is lined with Antimicrobial Silver Fibers which help eliminate the odor emitted from your body. I have nothing but good things to say about this stuff, and will likely never use anything else. That being said, I wash all my clothes, hunting clothes and regular clothes in ALL: Free & Clear Detergent, and use a scent free fabric softener. I also am very particular about keeping my boots scent-free or suppressed, and wear a thin neck gaiter over my mouth and nose to contain my respiratory tract scent that may be emitted. I cannot remember being "winded" in the last 3 yrs, and have had a few hundred deer within bow range during that period of time, including a few dandy bucks, only one of which I was able to close the deal on, but I do get close to them. I think beyond just having scent suppression clothing, you need to have a "Scent Suppression Discipline." X-Scent helps me with that.
