Cobras, a revolutionary interactive and connected t-shirt!

How does it work?

The Cobras t-shirt integrates sensitive sensors and interactive LEDs, making it the first connected combat t-shirt that responds in real time to the user's physical actions. Every hit is recorded and visually displayed thanks to innovative light technology, with data sent to a mobile app that creates a health bar reminiscent of classic video games.

An immersive experience

With connectivity to a dedicated mobile app, Cobras allows users to track performance, choose between different game modes, and compete with others. Accessible and intuitive, it encourages movement and fun without the need for complex equipment, making it suitable for everyone.

A step toward the future of sports

Cobras transforms the sports experience by combining digital and physical elements. Touch sensors replace direct contact for a risk-free practice, and the t-shirt suits both beginners and experienced athletes.

An app that tracks every hit in real time

When two players face off, the built-in sensors track each hit and display the points as a health bar. This intuitive interface makes competitions more engaging and brings together friends and families.

Comfortable and washable

Cobras’ embedded electronics are designed to be discreet and practical. Lightweight, breathable, machine washable, and with a futuristic design, this high-tech t-shirt is perfect for everything from casual fun to e-sports.

By combining technology and enjoyment, Cobras offers a unique experience that reimagines combat sports.
