The Decathlon SUBEA brand book you can read underwater
A gift for staff and investors that had to explain the brand in a few pages. We built it on one line: “Share the amazing underwater experience”.

Sound familiar?
If any of these sound like you, this project is about you.
- Your brand has a clear idea, but it lives in presentations nobody opens twice.
- You have to explain it to your team and to the people investing in it at the same time.
- You want your team to feel it as their own.
- And you’re after something people will want to keep.
That’s where Decathlon SUBEA came in.
Diving, for anyone
SUBEA, Decathlon’s diving department, wanted a Brand Book to give to its staff and investors: the essence of the brand in a few pages, and its idea of diving as something accessible, safe and enjoyable for anyone, not just experts.
Isla Studio built everything around one concept, “Share the amazing underwater experience”, which guided the art direction and every illustration. Besides the book, it made a video for the investor presentation, in the same visual universe.
How we solved it
Layered flat illustration in blues and turquoises, with real Decathlon users enjoying themselves underwater.

01 Share the amazing underwater experience
One line that organises everything
The concept opens the book and decides every illustration: what gets drawn, how, and in what tone.

02 Smooth and safe underwater experience
One value per page
Respect, inspiration, safety: each brand value has its own illustration and its own line.

03 Respect
Respect for the sea
A whale shark among divers: respect for the environment, told with one image and one word.

04 People, not kit
Faces of people enjoying themselves underwater: safety and enjoyment come before the equipment.
The object
Printed on stone paper
it can be read underwater
The book was printed on stone paper, which is waterproof: the brand can be read right where diving happens.
