Meet WHOOP 5.0 SportFlex

The WHOOP 5.0 SportFlex silicone band is designed to keep up with your most dynamic days. It combines rugged durability with a soft, skin-friendly touch, offering a hygienic surface that stays comfortable through long sessions, travel days, and everyday wear. The silicone finish is smooth to the touch and built to resist sweat and dirt while remaining easy to wipe clean between uses.

Built for high performance

  • Waterproof, sweatproof, and dirtproof silicone protect against sweat, rain, and splash moments during workouts.
  • Durable construction helps the band stay secure through high-energy movements and quick direction changes.

Soft-touch comfort and easy care

  • Ultra-smooth silicone feels gentle on skin and easy to rinse after activity.
  • Small scuffs wipe away, and for a deeper clean you can use isopropyl alcohol with a lint-free cloth, then rinse.

Adjustable, breathable fit

The adjustable closure ensures a snug, secure fit whether you’re lifting, running, or on the move, with ventilation details that help promote airflow and reduce moisture buildup.

Ready for water and high-sweat workouts

With 100% waterproof design, SportFlex stays reliable from lap swimming to surfing and intense interval sessions, making it a versatile accessory for aquatic or land-based activities.

Compatibility note

Care and maintenance tips

  • Rinse after saltwater or chlorinated pools to keep the silicone surface fresh.
