In 2018, on occasion of Milan Design Week, a new district was created: the Citylife District, which hosted for the first time the IN-OUT exhibition project, Wellbeing in outdoor, whose organization, direction and communication were managed by Promoest. An open-air exhibition event on the topic of wellbeing in outdoor with installations, prototypes, concepts and materials, an oasis of relaxation during the Milan Design Week 2018, which ran from April 17 to 22, 2018. IN-OUT wellbeing in outdoor was created thanks to the supervision of Architect Fabio Rotella, founder of the Rotella firm, in cooperation with Sergio Rossi, creator of the Sun exhibition in Rimini, with the media partnership of Topscape Paysage and and with the sponsorship of the City of Milan.

The exhibition was developed in the urban context of Citylife in the area of Piazza Tre Torri with exhibitors present both with large and small stands. With the strength of a shared concept and the synergy among the attending companies, a creative hub fully dedicated to the great outdoors was created, with attention to the topic of sustainability.
