    Heart Rate Monitor by COROS — recommended by Emi Stretton

    This product is for…

    Runners, cyclists, and multi-sport athletes who want accurate HR data without a chest strap—especially those who've had chafing, comfort, or reliability issues with chest straps. Data-focused athletes tracking effort across long or varied training are the core audience.

    Worth noting…

    Tattoos can interfere with optical accuracy, and hosts note a lifespan of roughly 24 months. Not suitable where instant HR response at the start of an effort is critical.
