Emotional durability
In order for a product to last, in addition to physical durability, design also needs to consider the product's ability to stay relevant and desirable to the consumer. WRAP have produced the Sustainable Clothing Guide to help with this.
Until recently, bag company Freitag offered a 'design a bag' feature on their website, allowing customers to choose their own materials and design layout, thus creating a strong bond between the user and the product.
