Make a Difference in Skin Diving! Key Points for Choosing a Comfortable Wetsuit

A Protective Layer for Your Skin

Skin diving is also a sport where you come into direct contact with nature, such as rocky shores, coral and sandy beaches. A wetsuit acts like a protective layer that shields your skin from tiny irritants such as jellyfish, as well as sunburn and abrasion.

Exposed areas such as the neck and arms are especially prone to cuts and inflammation, so choosing a wetsuit with adequate coverage is important for protecting your body.

Comfort Keeps Your Breathing Rhythm Steady

A suit that keeps you warm and fits with just the right amount of compression also has a positive effect on your breathing rhythm. In skin diving, calm breathing and relaxation matter more than anything. When your body temperature is maintained and you can move smoothly, your heart rate naturally stabilizes. A wetsuit is not just protection against the cold; it is an important layer that forms the boundary between your body and the ocean. That is why the suit you choose is directly linked to both comfort and safety.

Fit Is Everything

In skin diving, a wetsuit is essential equipment for minimizing water resistance. If there are gaps between the suit and your body, seawater gets in, drawing away body heat and making your movements feel heavy. On the other hand, if it is too tight, your breathing becomes shallow and it can be hard to relax.

To find that just-right snug fit, UMMY recommends detailed measurements. We pay attention to even slight differences in the neck, chest, waist and hips so we can deliver a fit that truly suits each individual. When the suit molds perfectly to your body, your movements become smoother and your breathing settles naturally.

Understanding Materials Makes a Difference in Comfort

Wetsuits are mainly made of neoprene (a rubber material), but softness, stretch and warmth vary depending on the surface finish and lining type. In skin diving, lightness and freedom of movement are key, so highly flexible materials are recommended.

UMMY's Long Spring and long-sleeve top styles also use these light, soft and comfortable materials. Because they do not pull or restrict you as you move underwater, you can fin kick and stretch without stress and dive in a more natural, relaxed way.

All UMMY wetsuits are Made in Japan, crafted by skilled artisans. By combining delicate cutting tailored to Japanese body types with high-quality materials, they deliver outstanding comfort.

Choose a Thickness That Suits How You Dive

The ideal wetsuit thickness depends on the water temperature and the season.

• Warm summer seas: around 2mm
• Colder waters in spring or autumn: about 3mm as a guide

Too thick restricts movement and too thin leaves you cold, so getting this balance right is important.

Rinse Off the Salt Right After Leaving the Sea

The salt and minerals in seawater can harden the fabric and rust metal parts. After use, it is important to rinse the suit thoroughly with fresh water as soon as possible. Take particular care around the zipper and neck, where salt tends to remain. Soaking the whole suit in a bucket or bathtub and gently press-washing it is effective. The key is to treat it gently, pressing the dirt out rather than scrubbing or wringing.

Dry Thoroughly in the Shade

After washing, dry it in a well-ventilated shady spot, away from direct sunlight. Turn it inside out to dry the inside first, then once it is completely dry, turn it right side out to dry the outside. This two-step drying method helps prevent moisture from staying inside.

Off-Season Storage Conditions

During periods when you will not use it for a while, it is ideal to store it hanging on a hanger, unfolded, in a well-ventilated place. If you must fold it, roll it loosely to avoid creases.

Trapped humidity can cause mold and odors, so placing a dehumidifier in the storage space is a good idea. Lightly dusting the suit with baby powder before long-term storage also prevents the fabric from sticking to itself.
