SPORT CAP COMBO combines a biotechnological concentrated odor capsule with a reusable SPORT CAP bottle that eliminates odors from sports gear and clothing. The SPORT CAP capsule significantly reduces plastic bottle use; just screw it onto an original SPORT CAP bottle filled with water and you're done ! Thanks to its formula containing specifically selected microorganisms, SPORT CAP biodegrades and accelerates the natural decomposition of organic matters responsible for the production of malodorous odors.  SPORT CAP treats odors at the source, instead of simply masking them. 24/7 long lasting permanent action, convenient to carry and requiring little storage space, the SPORT CAP capsule is phenomenal in eliminating performance odors from all athletes.
