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.

What is claimed is: 1. A device positionable within an interior region of an object to attract and accumulate moisture and odors emanating from the object, including: a compliant fabric sheeting permeable to air and water vapor and integrally incorporating an adsorbent component adapted to adsorb odor-causing constituents, said fabric sheeting being formed into a closed container; and a porous adsorbent desiccant in granular solid form, loosely occupying an interior of the container; the fabric sheeting being adapted to remove odor-causing constituents from air moving through the fabric sheeting toward the interior of the container whereby air reaching said interior is substantially free of the odor-causing constituents. 2. The device of claim 1 wherein: the porous adsorbent desiccant consists essentially of granules having diameters in the range of 2 mm to 8 mm. 3. The device of claim 2 wherein: the granules are non-uniform in size. 4. The device of claim 2 wherein: the granules are spheroidal beads. 5. The device of claim 1 wherein: the porous adsorbent desiccant occupies from about fifty percent to about ninety percent of a volume of said interior of the container. 6. The device of claim 1 wherein: the porous adsorbent desiccant is selected from the group consisting of: silica gel, activated aluminum oxide, and molecular sieves. 7. The device of claim 6 wherein: the porous adsorbent desiccant consists essentially of silica gel granules having pores with diameters in the range of 2-12 nm. 8. The device of claim 7 wherein: the pores have diameters in the range of 2-3 nm. 9.
