Product details

Overview

The WHOOP MG SportFlex is a silicone strap built for dynamic training and everyday wear. It blends a smooth, skin-friendly surface with a rugged, water-ready shell, designed to stay comfortable through workouts, swims, and outdoor sessions. This band emphasizes resilience and ease of maintenance, so you can focus on your routine rather than gear upkeep.

For users exploring health metrics, there is an optional ECG-read feature available with a WHOOP Life membership. A quick note: this version is not compatible with the Gen 4 device, so please verify compatibility with your current WHOOP model before pairing.

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.

  • Waterproof and sweatproof to support water-based workouts and hot, sweaty sessions
  • Durable silicone that resists dirt and grime during outdoor adventures

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.

  • Adjustable closure for a personalized, secure feel
  • Breathable design to reduce moisture build-up during workouts

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.
