    100% YAMAMOTO Neoprene - Why is this important?

    YAMAMOTO rubber is a high quality, warm, durable, lightweight and flexible rubber made from the purest Japanese limestone.

    The limestone that YAMAMOTO use is sourced from Mt. Kurohime, which stores billion tons of the purest Japanese limestone.
    Out of such purest limestone, YAMAMOTO only uses the highest-grade limestone, containing 99.7% of calcium carbonate. (The lower-grade limestone is used for cement.)
    Rubber can be made from Natural Rubber (NR) latex or petroleum oil. However, such raw materials are more likely to contain impurities. Therefore, its quality largely depends on production lot.

    TECHNICAL

     
     
    Nitrogen Gas neoprene

    NITROGEN GAS INFUSED CLOSED CELL

    The closed cells are packed together at an extremely high density and each individual cell is filled with nitrogen gas to prevent water penetration and increase heat retention. The nitrogen closed cell content is over 93% — over 30% higher than most competing materials — and with virtually no water absorption means the weight of this rubber remains nearly identical in wet or dry conditions, giving you more warmth than thicker wetsuits without the weight.
     
    honeycomb Structure

    HONEYCOMB STRUCTURE

    Yamamoto Corporation’s neoprene rubber is classified as (CR) “chloroprene rubber.” The special rubber incorporates an independent closed cell structure which adds high functionality including super light weight, high heat‐retention with good flexibility neoprene.

     
    low water absorption

    LOW WATER ABSORPTION = LIGHT WEIGHT

    Virtually no water absorption means the weight of this wetsuit remains nearly identical in wet or dry conditions, giving you more warmth than thicker wetsuits without the weight.

     

    SUSTAINABILTY

     
     
    wetsuit made from renewable energy

    Renewable Energy

    • Petroleum Oil

    Is expected to be depleted in next 50 years. Limestone, on the other hand, can be utilized for a wetsuit material semi-permanently.

    • Renewable Energy Sources

    When making CR from limestone, it requires a lot of energy. To reduce environmental impact, most of the energy used comes from renewable energy sources such as hydroelectricity.

    • Longer Product Lifetime

    As CR is excellent at performance such as weather resistance, CR wetsuits last longer.

    One of the most eco-friendly ways to achieve sustainability is to use one product for a longer time in order to facilitate that the product has to last longer.

     
    plant based oil wetsuit

    Plant Based Oil

    Although certain amount of oil is needed to make soft rubber foam, YAMAMOTO stopped using petroleum-derived oil.


    Instead, YAMAMOTO uses food-grade pure Canola oil, which is widely used as Tempura oil in Japan for sustainability and safety.

     
    ocean pollution

    Ocean Pollution

    Our beautiful blue sea is now in danger of being covered by marine debris.
    It is estimated that there are 150 million tons of plastic waste in the ocean and at least 8 million tons are flowing in the ocean annually.
    Reference: WWF Japan WEB site "About marine plastic problems"

    YAMAMOTO is working on recycled jersey materials to reduce pollution of the ocean and to let more people to be aware of this issue.

    It is estimated that the number of marina debris is going to exceeds the one of fish in 2050.

    YAMAMOTO will continue to work on solutions to conserve our beautiful ocean.

    FREQUENTLY ASKED WETSUIT BOOTS QUESTIONS

    • What countries do you ship to?

    • How do I care for my wetsuit and wetsuit accessories? (boots, gloves, mitts, caps)

      Wash it out with clean, cold water after every surf. Hang dry, not out in direct sunlight. Do not machine wash/dry. Don't use detergents.

    • Can I return my boots, gloves, mitts?

      Yes providing they have not been used or damaged. You are welcome to swap sizes if you didn't get it right first time. Return postage is your responsibility.

    • How does my wetsuit, boots, gloves, mitts work?

      Lunasurf wetsuits and accessories are awesome things, with today’s technology we can stay warm and have fun in the coldest of conditions. You can feel light, loose and warm unlike the wetsuits of yesteryear. Our wetsuits and accessories are 100% made using only the best Yamamoto Japanese limestone based neoprenes. That are then lined with a water/wind repelling buttery, stretchy lining that insulates you from the cold water water, air temps and winds. Your wetsuit, boot, glove, mitt is made up of panels of Neoprene. Wetsuits are not designed to keep you entirely dry. A small amount of water gets trapped between your body and the neoprene. Your body temperature then heats up this small amount of water giving you a nice warm feeling. This is why finding the correct fit is essential. Heat does eventually escape through the neoprene but very much like clothing the thicker the Neoprene the warmer you will be.

    • How do I find the right size boots for me?

      We have our own unique Lunasurf sizing for boots. Please refer to the size chart on the product page. It will explain further measuring up to find the perfect size Luna boot for you.

    • Is the 4mm boot ok for UK winters?

      Yes the 4mm boot was designed for UK winters. Men, women and children in Iceland, Norway and Scotland are doing full winters purely in the Lunasurf 4mm boot. If you are prone to the cold opt for the 8mm boot.
