sac/coupe folded as a bag all images are photographed by véronique huygue
questioning the basic form and properties of a bag, industrial design thibaut guittet has designed sac+, a collection of pieces that explore the object’s sustainability and function without breaking its efficiency. each sac has its own use while minimizing the amount of packing the consumer brings back home. all prototypes have been hand made in cotton fabric, leather and polyester by emeline raphanaud.
