Lunasurf Wetsuit Guide

We Only Use the Finest Materials

Sustainability

Our mission, create Affordable, Durable ECO friendly wetsuits.

Canola 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.

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.

Ocean Polution

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.

For Body & Earth

Testing

Since established in 1964, YAMAMOTO has been focusing on technologies for both eco-friendly and people-friendly materials.

The only downside of CR is its high price. Some rubber manufacturers actually mix other cheaper rubber such as NR or SBR to save the cost. We do not all our wetsuits are 100% YAMAMOTO Neoprene. By not dealing with lots of retailers we can offer premium wetsuits at an affordable price.

However, Limestone CR is obviously ideal as a wetsuit material in Quality, Sustainability, Performance, and Safety… Lunasurf is proud to be using YAMAMOTO Limestone Neoprene.

As surfers and having a limited number of retailers we can offer the highest quality wetsuits for an affordable price.

Skin Contact

The reason why YAMAMOTO has been committed to using Limestone Chloroprene Rubber (CR) is simply because our material comes into direct contact with human skin.
Unlike Natural Rubber, CR doesn’t contain latex which can cause serious allergic reactions.
It is all about safety and peace of mind.

Rubber products still can make up for the shortcomings by incorporating types of additives such as accelerator, anti-aging agent, anti-ozone agent, etc. However, it requires special attention to use such additives because some of them can cause allergies.

NR needs huge amounts of additives to compensate for its serious downsides.
Unfortunately, many allergies have been reported in the market.

In contrast, CR itself has good balance of performance. Therefore, CR doesn’t need a lot of additives, and it can minimise the risk.
Wetsuits exist to protect bodies and lives but NOT to damage them.

Tech Specs

Yamamoto#39

Super Light Weight ECO friendly Non-Petroleum based Japanese limestone neoprene with the perfect balance between warmth, stretch and durability.

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.

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

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.

Wetsuit Features

ECO Friendly Recycled Thermal Lining

Quick drying, comfy, thermal, silky smooth recycled linings makes for a snug, warm, lightweight, high performance wetsuit. We believe that to make a great wetsuit you need the best eco aware materials.

Quick Dry Lining

Quick-drying linings for easy convenience, with a silky smooth feel on the skin.

Glued & Blind Stitched (GBS)

Every seam has been glued and blind-stitched to reduce water entry and have excellent durability. Seams and panels have be strategically designed with flexibility and mobility as the focus Making for a non restricting comfortable wetsuit.

4-Way Stretch Tape

A thin comfortable 4-way high stretch neoprene tape. Placed on all interior seams minimising water entry and maximising warmth retention.

Dislocating Mini Zip

Effortless to take on and off. Easy front entry mini slant zip system, which dislocates making it easier to open up the entry and get in to your suit with ease. No unnecessary bulky zipper, our mini zipper means no unbalanced restriction or area of tension. Securely held closed with a popper.
