Techniques for producing an article having hollow structures are described herein. The disclosed techniques include weaving a plurality of yarns to form a woven fabric, wherein the plurality of yams each comprise a dissolvable core, and the dissolvable core comprises polyvinyl alcohol (PVA) having a water solubility; neutralizing an alkaline before drying the woven fabric to maintain the water solubility of the PVA; and washing the woven fabric or a garment made by the woven fabric to at least partially remove the dissolvable core.

A system that deodorizes gear, padding, or other apparel by killing the bacteria that cause odor. Articles to be deodorized are placed within a re-sealable airtight bag along with highly pure anhydrous ethanol. As the ethanol vaporizes, the gaseous ethanol readily dissolves within the aqueous environment that envelops the bacteria. Ethanol levels within this moisture gradually increase and eventually become bactericidal.
