ScentBlocker Plus utilizes powdered carbon. We use powdered carbon instead of granular carbon because the overall surface area available that can adsorb odor is increased substantially in size and efficiency. Granular carbon also has a propensity to dislodge due to abrasion leaving a relatively large hole in the carbon media. Powdered carbon does not. Permeability of the garment the carbon fabric and the total garment construction method must accommodate a high level of breathability.
Human odor is a gas that is carried through the air.
This odor can only be adsorbed if it can reach and contact the carbons. A common misconception is that carbon clothing cannot be washed. The truth is that all hunting garments must be washed to eliminate odor contamination on the outer fabric. ScentBlocker Plus is washable. Washing is required before initial use of the garment and recommended only as needed for the life of the garment.
