Specially formulated to remove the sweaty smell from synthetic fabrics, especially technical apparel used for running, cycling, yoga, tennis, soccer, football, and other sports. The residues in sweat bond to synthetic fabrics differently than they do to natural fabrics, so regular detergents are not effective at removing those residues. Win's special formula is optimized for synthetics, removing the resides and getting the smell out. Win is color safe, septic safe, and biodegradable. It is safe for all tyoes of fabrics although optimized for synthetics.
