Griffin Technology (http://www.griffintechnology.com/) and Chilewich (http://www.chilewich.com/) have expanded their collaboration with the introduction of Elan Form Chilewich, Rib Weave, for iPhone 4/4S.

The new collection features Chilewich’s Rib Weave vinyl, a chunky, textural weave of flat, dry colors that has a natural feel despite its durable, synthetic material, according to George Campbell, director of Industrial Design at Griffin. An impact-resistant Griffin-engineered shell provides the foundation of the case.

Chilewich’s Rib Weave is wrapped around the shell. The low-profile case design accommodates most charging docks and is easy to keep clean, Campell says.

The new Elan Form Chilewich, Rib Weave, is now available in five colors — black, coconut, mahogany, pearl and toffee — and will retail for $39.99 at Apple Retail Stores and online at Chilewich.com and GriffinTechnology.com.
