DID YOU KNOW
A SUMORING FREEZES AT 18°C?

This is because of the PCM technology inside the ring.
It’s a natural cooling agent, easy to use, and can be used repeatedly.

PCM (Phase Changing Material) was invented by NASA.

A Sumoring

HOW IT WORKS?

Simply put the Sumoring inside your freezer, fridge, in ice-cold water, or near your air conditioning, and it will start to crystallize. When it’s hard, you can put it around your neck.
How to activate your Sumoring
At the beginning, after activating a Sumoring, it will feel very cold, but not icy cold—don’t worry. After a couple of minutes, the ring will absorb your body heat and release cold for up to 90 minutes, giving you a comfortable cooling sensation.

Even when it’s melting inside the ring, it will still calm down your body heat.
There will be no dripping or condensation when melting or wearing the Sumoring.

Once the cooling effect is over, you can reactivate the Sumoring again by placing it in your fridge, freezer, in cold water, or near your air-conditioner.

You can do this as many times as you want.

The Sumoring is reusable!

Sumoring works by cooling down specific areas of the body that are more sensitive to temperature changes.

The neck is one of these key areas, and cooling it can significantly help regulate body temperature and prevent overheating.

This ensures you stay comfortable even on the hottest moments.

So, put on your Sumoring
and BEAT THE HEAT!
