The Classic shorts, the Springer, Setter, Bulldog and Dane II, are indeed suitable for use in saltwater and chlorine. Our material is tested to 50mg of chlorine per litre of water, while the average pool should have 14mg. Our shorts have also been tested for saltwater and oil. We have had some complaints of staining due to uncommon substance, such as copper, from pools in Greece and Turkey. As with most fabrics, ours is not stain resistant. Please note our Sport collection is not as resistant to chlorine, and we, therefore, advise use only in saltwater.
