WHOOP 5.0 SportFlex – Waterproof Silicone Band for Health, Fitness, & Wellness

Meet the WHOOP 5.0 SportFlex, a silicone band built to keep pace with your most demanding workouts and daily wellness routines. It combines rugged durability with a comfortable, skin-friendly feel, so you can focus on performance without distraction. The SportFlex is designed to be waterproof, sweatproof, and dirtproof, making it a versatile companion for water-based activities and high-sweat sessions alike.

Why SportFlex stands out

Designed for high-performance wear, SportFlex uses a silicone composition that resists water, sweat, and dirt. This means you can push through tough sets, long runs, or outdoor adventures with one band that keeps its shape and feel.

• Durable, all-weather silicone: Waterproof, sweatproof, and dirtproof, built to endure intense workouts and adventurous days.
• Soft-touch feel: Ultra-smooth on the skin, hygienic, and easy to clean after tough sessions. Small scuffs wipe away, and a deeper clean is simple with isopropyl alcohol and a lint-free cloth, then a water rinse.
• Adjustable and breathable: A secure closure system pairs with ventilation details to stay snug without sacrificing airflow during long workouts.
• 100% waterproof: Fully waterproof, making it suitable for swimming laps, surfing, and high-sweat activity alike.
• Compatibility note: This band is not compatible with WHOOP Gen 4.

Real-world use and care

Whether you’re training in the pool, riding waves, or powering through a high-intensity interval session, SportFlex aims to stay in place and feel comfortable. The breathable design helps reduce friction during extended wear, while the secure closure helps you focus on form and effort rather than adjustments.

• Swimming, surfing, and other water-based workouts with a reliable fit.
• HIIT, cardio, and outdoor activities where sweat and movement are part of the routine.

To keep the band looking and feeling its best, wipe it down after workouts and perform a deeper clean when needed. For a thorough refresh, use isopropyl alcohol on a lint-free cloth, rinse with water, and allow to air dry before reattaching.

Care tips and fit

The SportFlex band features an adjustable closure and breathable construction, making it easy to tailor the fit for comfort during long sessions. Regular cleaning helps maintain its hygienic feel and keeps the silicone looking fresh over time.
