A new series of recovery mats is now available! The mat thickness is now 4mm, making it slimmer. 4mm diameter is about 10cm 5mm diameter 12cm, so it is slim when you roll it up to about 1.5cm-2cm. The cushioning and grip are the same as 5mm, and since it is highly resilient, even 4mm is sufficient for cushioning. And it is even lighter, weighing less than 1 kg at 950 g Japan's largest comparison verification site "mybest" yoga mat category NO.1 Yoga mat created by Japan technology that considers health and the environment Feature 1 "EVA × rubber hybrid" EVA material (ethylene vinyl acetate copolymer) × rubber hybrid material. EVA material is stronger than PVC (polyvinyl chloride) and TPE material, and is resistant to water and lightweight. It is also a versatile material that is environmentally friendly and does not emit harmful substances even when burned. This EVA is a material that is further advanced by blending rubber with more elastic, improving durability, cushioning, and flexibility. Feature 2 "An evolved version of the air rubber created by Japan to the world" The strongest and most flexible material in the "Air Rubber Series" developed by Buntaro (a manufacturer of insole materials founded in 1948 for 70 years) has been developed as a rubber for walking for a long time and has been supporting people's feet for many years. The material feels gentle and smooth as if it gently wraps around the human body. Also, as the name suggests, it has a lot of air bubbles and is as light as air. This technology was born in Kobe, Japan, and is a material filled with Japan technology that has not yet been reproduced in the world. Feature 3 "Memory × high resilience" A material with two contradictory characteristics that are impossible to normally × a memory foam. When stepping on the mat, it has "memory foam" and when it leaves the mat, it supports body movement firmly when exercising on the mat. Feature 4 "Hygienic material that does not allow water to seep in" The biggest feature of the mat is that each mat is made up of independent air bubbles, so it is an excellent hygienic material that prevents water from penetrating and does not grow bacteria such as mold. In addition, it is a versatile material that can prevent water penetration while minimizing slippage due to sweat and other factors due to fine surface bubbles. Feature 5 "Rice cake-like feel and high grip" The blend of fine air bubbles on the numerous surfaces and rubber ensures that common yoga mats have no unevenness to prevent slipping, and have a comfortable feel like "rice cakes" and fine air bubbles on multiple sides, resulting in many friction surfaces and high grip. Supports hard poses with versatile grip Feature 6 "Restore body functions" Physical therapists were also involved in the development of this mat, and the material development focused on how people use their feet. The mat's grip and memory foam adjustment allow the toes (toes) that humans often use to "step on" naturally. The movement of the toes, which is being lost by modern people, is actually very important, and if it is not used, it may lead to a decline in the longitudinal arch, bunions, etc., and may cause walking disorders. Using your toes can also help you recover from fatigue and improve blood flow, which can help balance your overall health. The biggest feature is that by continuing to use the mat, the body recognizes the movement of the toes that are being lost, and while improving the accuracy of yoga and other automatic exercises, it recovers the entire body and continuously puts the whole body in a healthy state. Feature 7 "Upcycling to circulate things" As an initiative to prevent wasted things, we will collect mats that are no longer in use, grind them into small pieces and regenerate them into beads such as cushions, and use the crushed resources into new materials that can be used in chairs and shelves by hardening them into plates. *Please refrain from using this product for purposes other than yoga mats. *If you are concerned about dirt or other issues after use, please clean it with a wipe. After cleaning, please store it in a well-ventilated place. Also, once you have confirmed that the mat is completely dry, we recommend that you roll it into a tube and store it. *Due to the nature of the material, there are individual differences in marble patterns, and there may be areas with a dark pattern or parts that are close to plain colors (areas with thin patterns).
