Residues left by regular detergents trap moisture which cause odor, and block ther performance-enhancing features of your gear. Penguin Sport-Wash is no regular detergent. Its residue-free, non-allergenic formula is deisgned to keep high-tech fabric at peak performance and odor-free by washing away residues left by regular detergents, removing dirt, neutralizing bacteria, and restoring breathability, moisture-wicking, and factory applied waterproofing (DWR). It's also biodegradable, so your conscience is as clean as your gear.
