This bicep band is compatible with WHOOP 5.0, One, Peak, and Life devices, offering a secure and comfortable alternative to wrist-worn straps. Made from lightweight woven nylon, it feels soft on the skin and remains breathable during long workouts or daily wear. The metal U-shaped connector helps keep your tracker securely in place, minimizing movement during high-intensity activities such as running, strength training, cycling, or HIIT. The strap measures approximately 39 cm (15.35 inches) in total length, providing a wide adjustment range suitable for most men and women. Designed with a loop-style construction, the band can be worn on the upper arm or forearm, giving you flexibility to choose the placement that feels most comfortable for your training and tracking needs. Sweat-resistant, quick-drying, and built for durability, this replacement arm strap is well suited for gym workouts, outdoor sports, and everyday use. Whether you prefer a wrist-free setup or need a more stable option during intense training, this bicep band offers a reliable and comfortable fit for your WHOOP device. Please note: this band is not compatible with WHOOP Gen 4 devices.
