LDFAS Silicone Sport Band for Whoop 5.0 / MG | Black & Light Gray

Compatible with both Whoop 5.0 and Whoop Medical Grade (MG) — the LDFAS Silicone Sport Band is engineered as a direct-fit replacement for the redesigned Fast Link clasp on Whoop 5.0 and MG wearables. One band, two devices. Not compatible with Whoop 4.0 — the 4.0 chassis is 7% larger and uses a different clasp. Whether you wear your Whoop for sleep tracking, marathon training, or 24/7 medical monitoring, this breathable silicone strap keeps the sensor locked to your skin without irritation. The soft-touch exterior pairs with a perforated inner channel for airflow, so the band stays comfortable during hot yoga, overnight HRV collection, and the sweatiest interval sessions. Why Choose the LDFAS Whoop 5.0 / MG Band Dual-Device Compatibility — Custom-molded clasp fits Whoop 5.0 AND Medical Grade (MG) exactly. ECG, sleep, and recovery sensors remain fully exposed and accurate. Breathable Perforation Pattern — 8-row ventilation grooves along the inner lining reduce moisture build-up and chafing. Tested across 24-hour wear cycles. Skin-Safe Silicone — PMU-free, latex-free, hypoallergenic formula. Safe for sensitive skin and post-shave wear. Waterproof to 50m — Shower, swim, and surface-water safe. Salt-water rinse recommended to extend band life. One-Click Fast Link Swap — Tool-free installation in under 5 seconds. Swap bands to match outfit, workout, or sensor placement without removing the Whoop pod. Anti-Stain Finish — Wipes clean with isopropyl alcohol or mild soap. Resists dye transfer from denim, sweat, and self-tanner.
