For winter snorkeling on Miyako Island,A full-body suit measuring 3–5 mm that covers the arms and legsIf you choose this, you'll be less likely to feel the cold.
Since the warmth of a wetsuit depends on its shape and the thickness of the fabric, be sure to choose one that's appropriate for the time of year you'll be traveling.
| type | 形 | Best Time of Year |

| Spring | Short-sleeved shirts and shorts (long-sleeved shirts and shorts are also available) | April and November |

The thickness of the fabric is,In winter (December–March), 3–5 mm; in spring and fall (April and November), around 3 mmThis is a general guideline.
The thicker the wetsuit, the warmer it is, but it also makes it harder to move around. So, if you tend to feel the cold, you should choose a 5mm wetsuit, and if ease of movement is your priority, a 3mm wetsuit is a good choice.
