American wearable technology company WHOOP has unveiled the CR7 SuperKnit band as part of its collaboration with football legend Cristiano Ronaldo.

Designed with Ronaldo’s signature branding, the band is compatible with WHOOP 4.0. Crafted from WHOOP’s durable SuperKnit material, the bands come in “Home” and “Away” colorways, symbolizing Ronaldo’s global football career.

Based in Boston, WHOOP is known for its fitness trackers, widely used by athletes to monitor health and performance. Ronaldo partnered with WHOOP as an investor earlier this year, joining prominent athletes such as Patrick Mahomes, Michael Phelps, Eli Manning, and Rory McIlroy.

WHOOP’s product evolution includes the launch of WHOOP 4.0 in 2021, featuring enhanced battery technology from Sila Nanotechnologies. The device collects data on sleep, heart rate variability, respiratory rate, and resting heart rate to generate a daily recovery score ranging from 0% to 100%, helping users balance exertion and rest.

In September 2023, WHOOP launched its “WHOOP Coach” feature, powered by OpenAI, offering users personalized fitness and health guidance and enabling members to ask tailored questions and engage in conversations about their training and overall health.
