Tropicfeel Shell

A unique, distinctive and versatile backpack that won a Red Dot Best of The Best award.


Bringing industrial design and fashion design together to devise the smartest way to travel

The Shell project has been a huge challenge: to do something that all backpack brands try and fail to do. On the one hand, to save space, and to do so at times as different as a trip or a day out of the office. And on the other hand, to improve the user experience compared to existing products on the market.



Backpack interior design to enhance the user experience when travelling

The day-to-day running of the project has been based on continuous collaboration. Our team of industrial designers, fashion designers and engineers worked in constant contact with Tropicfeel and its users. Only in this way have we been able to validate that the design proposal meets all market and user requirements.



Kickstarter campaign launched with €2m raised for the Shell backpack

With a disruptive design, Shell allows you to carry everything you need to spend a day away from home and, at the same time, pack enough clothes to go on a two-week trip anywhere in the world, saving up to 20% of space. With all these features, the launch of the product on Kickstarter has reached a fundraising figure of 2 million euros.

Study the needs of users on each journey to achieve the perfect fit.

We started the project from a very in-depth user study that established the objects that people take with them on all kinds of trips: to the office or to study, on a short weekend getaway and on long journeys. With all the objects clearly defined, we began the conceptualisation of the backpack, with the aim of ensuring that all the things that users carry have their own space in the most orderly and useful way possible in a single bag.

After creating and testing 8 prototypes and involving more than 5,000 users in the iteration and refinement process, we have achieved an attractive, functional and durable product that meets the objective we set at the beginning of the project.
