Great Question. Your last layer is the most important one. (last chance to eliminate odor) If it has been washed in scent free detergent and then put in a scent free atmosphere its not going to hold any human odor until used. Then it will pick up any odors present. That's where the magic of carbon , silver,etc shines. It will contain those odors until released in the dryer . Ozone dry wash setups destroy any other odors and can be used in conjunction with carbon,silver clothing like Scent Lok. Its a system and I wear NOTHING that has not been treated with ozone and is Scent Lok or Scentblocker. I wear a base layer when I get out of the shower and scent free clothing until I get to my spot. I take my gear out of my OZ bag (everything including cell phone,release, hawl line, steps, roping etc. Everything I bring in with me has been in that bag and is scent free. I usually wear three or more layers and place any clothing articles , wipes, etc in plastic bags inside my scentlok Rogue bag which was also in my dry wash bag. If you are taking it in with you then it should be treated. That includes your bow and arrows. Everything. Sounds difficult and tedious but in the end it's I feel it`s worth it. Hunts over. Put everything you can back in the bag and cycle it on the way home. By the time you home everything in the bag will again be odor free. Good Hunting Red Beard.
The newer clothing has new technology (antimicrobial) that eliminates the need to do that. I wear scentblocker 1.5 base layer or scentlok equivalent. I then put on my Summit weight Scent lok Thermal layer . I then put on the camo outer layer (scentlok/Scentblocker) . Head cover,face mask,gloves, all scentlok. Boots rubber lacrosse . I even use carbomask camo paint which has activated carbon absorbing qualities. This system really works for me and it will for you.
