Additional Care Tips

  • Machine wash cold (30°C/85°F) on gentle cycle — polypropylene has a very low melting point
  • Never tumble dry or iron — polypropylene melts at temperatures as low as 130°C/265°F
  • Line dry only in shade — direct heat from any source can damage the fiber
  • Wash after every wear — polypropylene retains body odor more than most synthetics
  • Avoid bleach and fabric softener; use a sport-specific or enzyme-based detergent for odor
  • Store flat or folded; polypropylene does not wrinkle and maintains its shape well
