SIGVARIS Introduces the Athletic Recovery Sock

Peachtree City, GA – On October 29, 2009, SIGVARIS introduced the Athletic Recovery sock, an Active Therapy medical compression garment designed to improve athletic recovery and performance. The Athletic Recovery sock helps to flush out the lactic acids built up in the leg muscles during exercise, as well as relieve tired, aching legs and exercise-induced muscle soreness.

SIGVARIS created the Athletic Recovery sock for competitive athletes and weekend warriors as compression garments have become highly visible in all major sports. Whether it’s during the actual event, after the event, or even while traveling, athletes are making graduated compression socks part of their everyday attire.

“As the global leader of graduated compression socks, we are very excited to be entering this new and emerging market segment of Athletic Recovery. SIGVARIS brings unequalled quality and expertise to a new demographic of competitive athletes and weekend warriors, many of which may have been previously unfamiliar with graduated compression garments. The Athletic Recovery Sock is the first SIGVARIS product in the new Active Therapy series, with several additional products to be introduced in 2010”, said Jonas Thelin, Director of Marketing, SIGVARIS North America.

The Athletic Recovery sock is made of drirelease® yarns to accelerate the water release rate of wet fabric, and includes environmentally-friendly FreshGuard to eliminate odors by blocking odor-causing sebaceous body oils from attaching to the fabric.

Additional Athletic Recovery sock features & benefits include:

  • Lactic acid flush-out and relief of delayed onset leg muscle soreness
  • Superior Athletic Sizing Assortment, comfort and fit with 50+ years of graduated compression expertise
  • Patented drirelease® and latex-free yarns with an embedded environmentally-friendly Freshguard® treatment that virtually eliminates odors
  • True Graduated Compression from the global leader of graduated compression socks

SIGVARIS created to provide consumers with information on the new Athletic Recovery sock, as well as a forum for athletes to discuss their compression therapy experiences and results. The website also includes related medical studies that support the science behind the use of compression therapy for athletic performance and recovery.

Optimer Brands, formerly known as Optimer Performance Fibers, a Sterling Capital Partners company, is based in Wilmington, DE. Founded in 2001, Optimer Brands conducts textile research, development and marketing and has a scientific staff credited with over 100 patents and developments.

drirelease is a registered trademark of Optimer Brands. It is a patented, intimate blend of synthetic (hydrophobic) and nat ural (hydrophilic) fibers that accelerates the water release rate of wet fabric. Rather than spreading the moisture across the surface of the fabric, drirelease actually pushes it to the outside of a garment, releasing water and perspiration faster than any other performance fabric on the market. drirelease includes the added benefit of FreshGuard, an odor neutralizer embedded in all drirelease fabrics, that virtually eliminates odor without using harmful chemicals and won’t wash out.

FreshGuard is a registered trademark of Optimer Brands. It is an odor neutralizer embedded in all drirelease fabrics. It eliminates odors in garments by blocking odor-causing sebaceous body oils from attaching to the fabric — also stopping the attrac tion of odor-causing bacteria. Not an anti-microbial or anti-bacterial, which attack bacteria that possess positive functions, FreshGuard is friendly to the environment.
