Allied Feather & Down, a company based in Los Angeles that describes itself as the largest supplier of down for the outdoor industry, has developed a new antimicrobial treatment, called Allied Refined Down, to protect apparel and equipment used in rough environmental conditions, including camping, hunting and fishing, against the growth of bacteria and bad odors. Developed and tested for more than a year through two different independent laboratories, the new treatment is said to be particularly well suited for warm weather and exposure to moisture in activities such as walking through marshy areas. It is available now.
