SportFlex engineered for high-performance wear

Meet the WHOOP MG SportFlex—the silicone band built to keep pace with your toughest workouts and daily adventures. The silicone is waterproof, sweatproof, and dirtproof, offering durability without compromising comfort. Wear it through runs, HIIT sessions, swims, and beyond, and notice how the band holds up under sweat, splash, and repeated flexing.

Soft-touch silicone you can feel

The material is ultra-smooth and hygienic, designed to be easy to wipe clean. Small scuffs can be wiped away, and a deeper clean with isopropyl alcohol, a lint-free cloth, and a rinse can restore its fresh appearance.

Adjustable and breathable for a secure fit

  • Adjustable closure ensures a snug fit during dynamic movement
  • Ventilation details promote airflow for comfort during long sessions

Completely waterproof, ready for pool, beach, or rain

Water resistance means you can wear SportFlex through laps, surfing, or high-sweat workouts without fear of moisture seeping in. It’s built to withstand repeated exposure to water and sweat.

ECG compatibility option with Life membership

For users who opt into WHOOP Life, SportFlex offers an on-demand ECG reading capability. This feature is described as an option rather than a guarantee.

Compatibility note

  • This band is not compatible with WHOOP 4.0

Care and maintenance

To clean, wipe with a lint-free cloth and rinse with water. For deeper cleaning, use isopropyl alcohol and repeat rinse.

Real-life use scenarios

Picture this band as a ventilation-friendly companion for a morning swim, a humid gym session, or a run in the rain. Its silicone texture remains comfortable against the skin while you focus on pace and form.

  • Swimmers and water athletes can rely on waterproof construction
  • Outdoor and heavy-sweat workouts benefit from sweatproof durability
  • Travel days stay hassle-free with easy cleaning and quick maintenance
