Remove your shorts and launder asap for best results as residual sweat may damage the chamois. Wash only in delicate cycle at 86 degrees. Use neutral non-aggressive detergents, keep like colors together and avoid dryers. If you use chamois butter/cream, your garment's ability to wick moisture will be greatly reduced and the durability of your chamois may be compromised. Note: we recommend that you wash new bottoms prior to use.
