Sumoring

SUMORING is an innovative neck cooler designed to deliver long-lasting relief. Using advanced PCM (Phase Change Material) technology, it cools faster and stays cold longer than conventional cooling solutions. The liquid inside the ring crystallizes at temperatures below 18°C, providing up to 90 minutes of continuous cooling after activation. From CrossFit enthusiasts and kids on vacation to city trippers, festival goers, outdoor workers, office workers trying to stay comfortable at their desks, and even managers needing to stay sharp during presentations. Chefs in bustling kitchens, pregnant women seeking comfort, migraine patients and women in their menopauzes beating hot flashes. Cold therapy offers a natural way to feel more at ease, recharge, and regain focus. SUMORING fits seamlessly into anyone’s lifestyle, making it a versatile and essential accessory.
