    This product is for…

    Trail and ultra runners who run at night, especially those prone to headaches from headlamps or who struggle with night vision. Pairs naturally with UltrAspire's Mountain Racer belt for an integrated carry setup.

    Worth noting…

    The wide front band is flagged as key to comfort — prevents stomach pressure during long efforts and keeps the light stable. Battery is rechargeable and noted as swappable on the move.
