KEEP YOUR CLOTHES FRESHER LONGER. We've added biocide-free antimicrobial technology to our great-looking apparel to help control odor. Tiny microbes cause stains, deterioration, and unpleasant smells that stick to your clothing. This technology creates a non-hospitable environment for microbes so there is no odor from the start. Our process is free of heavy metals and nano particles that can harm the environment. So not only do you smell good, you feel good, too.
