48results about How to "Reduce odor emission" patented technology

An article of clothing adapted to be worn by a person has an odor absorbing substance incorporated therein. The odor absorbing substance absorbs odors emitting from that portion of the person which is substantially surrounded by the clothing. Reduction of odors emitting from a person wearing the article of clothing will help to avoid detection of the wearer of the article of clothing by many species of wildlife having an acute sense of smell.

An odor absorbing system for use by a person to reduce odor emanation from the person into an environment surrounding the person includes an article of clothing that is configured to be worn by the person and an odor absorbing insert removably attached to the article of clothing. The article of clothing includes a base layer that is adapted to substantially surround a portion of the person wearing the article of clothing. The base layer includes a vent. The odor absorbing insert is configured to cover the vent and includes a layer of breathable material and an odor absorbing agent on the layer of breathable material.
