It’s always good to see a company take an alternative approach to a problem. Kokatat have down just that with the Idol dry suit. Essenstially the Idol is a two piece suit that is a joined by a waterproof zip that circumnavigates the waist of the suit. This means that the top could be used as a dry top or used in conjunction with the bottoms to form a complete suit. A great idea.
