A Must-Read for Skin Diving Beginners: Why Long Spring Wetsuits Are So Popular, Plus the Best Thickness and Material

Why Long Springs are chosen: the balance of mobility and protection

A Long Spring covers part of the arms and legs without restricting your joints' range of motion, combining freedom to swim with body protection. It's not as thick as a full suit and is easy to put on and take off. You can wear it as lightly as swimwear, yet it keeps you warm and protects your skin from chafing and sunburn. It truly is smart wear for enjoying the ocean.

The less experienced you are, the more your clothing affects your sense of security

On your first skin dives, it's natural to tense up. At times like that, simply wearing something that wraps your skin securely greatly boosts your peace of mind.

With a Long Spring that offers a good balance of warmth, protection and mobility, even beginners can focus on the underwater world without unnecessary stress. Light and easy to move in, yet reassuring: that is why so many skin divers choose a Long Spring.

What a Long Spring needs: harmony between material and thickness

The key to choosing a comfortable Long Spring lies in the balance between the material's stretch and its thickness. Too thick and it hinders movement; too thin and it lacks warmth. In a sport like skin diving, where subtle breathing and movement matter, getting it just right determines your performance.

Proudly MADE IN JAPAN: the UMMY × Mellow CANDY series

Born from the pursuit of the ideal fit, CANDY is the UMMY × Mellow Long Spring. Every process, from material selection and pattern making to sewing, is done in Japan (MADE IN JAPAN), with a design carefully thought out for the body shapes and movements of Japanese divers. Its soft, enveloping feel lets you experience stress-free comfort from the moment you put it on.

The sense of unity, like an extension of your own skin, is a quality only UMMY, with its own factory in Japan, can deliver.

When trying it on, check these three movements

To evaluate the fit rigorously, check the following movements.

• Rotate your shoulders: is there any tightness across the range of motion?
• Bend forward and backward: is there any unnatural gap at the back or waist?
• Take a deep breath: can you fill your lungs smoothly without feeling pressure on your chest?

Ease of breathing in particular is the most important factor, directly linked to safety. If anything feels even slightly off, take it as a sign to reconsider the size.

When buying online, pay attention to your body proportions

Refer not only to your height and weight but also to your shoulder width and torso measurements. UMMY products are designed based on Japanese body types, so they are less prone to the size mismatches that are common with overseas brands. Use the detailed size guide to choose a suit that matches your frame.

If in doubt, slightly snug is best

Wetsuit material (neoprene) has the property of conforming to your body once it's in the water. If it feels a little tight when you try it on, that is the best size underwater. Anything with extra room on land will become baggy underwater and let water in, which makes you cold, so be careful.
