Performance and durability

SportFlex is engineered to endure high-intensity activities. The silicone is waterproof, sweatproof, and dirt-resistant, giving you a dependable companion from weight room circuits to open-water sessions. The band’s durable construction is designed to resist typical wear from vigorous movement and exposure to elements.

Comfort and care

The soft-touch silicone offers a smooth, hygienic feel against the skin. It’s easy to wipe clean, and small scuffs can be addressed with a quick wipe or a deeper clean using isopropyl alcohol and a lint-free cloth, followed by a rinse.

• Ultra-smooth silicone surface for comfortable daily wear
• Ventilation details help the strap breathe during longer sessions

Secure fit and Versatility

Designed with an adjustable closure, SportFlex provides a snug, secure fit whether you’re sprinting, swimming, or practicing yoga. The form factor supports a range of activities while remaining light on the wrist.

ECG readiness is available as an option with the Life membership, enabling on-demand readings when you need them. Remember: not compatible with the Gen 4 WHOOP device, so confirm your model before purchasing.
