Yamamoto limestone rubber is superior and eco-friendly, offering better flexibility, durability, and insulation than petroleum-based neoprene. It's more sustainable, reducing oil dependence and carbon footprint. YAMAMOTO uses 99.7% pure limestone from Mt. Kurohime, Japan, and manufactures with renewable energy. The resulting neoprene has a high-density micro-cell structure.

Yamamoto limestone rubber provides increased stretch, better heat retention, and improved resistance to abrasion. This translates to a more comfortable and efficient wetsuit, allowing for extended sessions in the water. The rubber's eco-friendly production process also aligns with environmentally conscious values

1. Improved Insulation: Limestone neoprene can be formulated to have smaller and more consistent closed-cell bubbles, which trap a greater amount of insulating air. This helps to retain body heat and provide better thermal protection in colder water.
2. Greater Flexibility: Limestone neoprene is known for its high stretch and flexibility, which can create a better seal against the skin. A snug and well-fitting wetsuit minimizes water circulation inside the suit, thus helping to maintain a warmer body temperature.
3. Reduced Water Absorption: Limestone neoprene tends to have lower water absorption compared to petroleum-based neoprene. This means that less water is trapped inside the wetsuit, reducing the cooling effect of evaporative heat loss.
4. Eco-Friendly Properties: In addition to its warmth benefits, limestone neoprene is often considered more environmentally friendly due to its production process, which reduces dependency on petroleum and decreases the carbon footprint.
