Carhartt WIP is teaming up once again with Dutch accessories brand Ikku for a new collection of protective laptop and tablet sleeves. Dubbed the “Sierra Collection,” the new pieces embody both brands’ penchant for clean and sophisticated design. Here, Carhartt and Ikku make extensive use of a deep black organic cotton canvas, with subtle ribcord accenting the sides, and a colorful burst of cactus print for contrast. The use of organic cotton in particular sets this collection apart, as it creates a product that’s both environmentally friendly, yet remarkably durable at the same time. The “Sierra Collection” is available for 13” and 15” Macbook Pros, as well as iPads and iPad minis. Look for them now at select retailers, including the HYPEBEAST Store.
