Abstract
An insert for sports gear and footwear has a compliant casing formed of fabric sheeting that incorporates regions of fused or otherwise integral regions of activated carbon. A desiccant such as silica gel in the form of spheroidal beads or other granules is loosely enclosed inside of the casing. The activated carbon has an affinity for odor-causing constituents such as organic compounds, and extracts airborne odor-causing constituents as air enters the casing. Inside the casing, the desiccant extracts airborne water vapor. The two-stage removal of odor-causing constituents and water vapor rapidly and effectively extracts moisture and odors. The silica gel and activated carbon are porous and have high surface areas available for adsorption, whereby the insert is adapted to maintain moisture and odors at low levels during long-term storage.
