Stay Secure. Across Your Activities. Whether you're tackling a mountain trail, pushing through a workout, or simply going about your day, your band should be the last thing on your mind. This replacement band compatible with WHOOP 5.0 and MG is designed to stay secure, hold up, and keep you comfortable through the demands of your day. Dual Locking. Less Distraction. A metal clasp locks the band in place first. Then a front hook-and-loop cover folds down for a second layer of security. The result is a stable, secure fit that helps keep your band in place during intense activities — so you can stay focused on what matters. Breathe Easy. Move Freely. Soft, lightweight nylon with ventilated inner channels keeps air flowing across your wrist. Whether you're deep into a workout or wearing it all day, the flexible, skin-friendly material moves with you and stays comfortable for extended wear. Built Tough. Built to Last. Abrasion-resistant rugged nylon paired with stainless steel hardware, built to handle daily wear and demanding conditions such as sweat, rain, and daily friction — with reliable, consistent performance. A Clean, Stable Fit. The ergonomic stainless steel contact groove helps maintain consistent sensor contact for WHOOP 5.0 and MG devices, helping keep your tracker securely positioned on your wrist. Compatible with WHOOP 5.0 and MG. Easy to install, no tools required. ⚠️ NOT compatible with WHOOP 4.0 (Gen 4).
