About the product

Made into a standard product in response to numerous requests

"Sen RED" has never had a size for boys until now.

Due to numerous requests for a special order for a boys' size, it was commercialized in 2025.

Lightweight and excellent shock absorption

Almost the same specifications as the general-purpose "Sen RED"

The 8mm wide stitching makes it soft and elastic, and it is also resistant to blows, so it can be used for both practice and matches.

This is the perfect armor for young swordsmen who want to improve their performance in matches.

Kote gloves are also very popular as a single item.

It is comparable to the custom-made combat-style Kote, making it easy to turn your wrist and transmitting the delicate movements of your hand and fingers to the Shinai.

It is designed to be easy to grip even for young swordsmen who still have difficulty with fine motor skills.

Special cut that doesn't restrict lower body movement

The center of the belly band is 8mm deep, and the left and right pelvis areas along the extension of the thighs are 4mm deep, diagonal stitches.

This special cut does not interfere with movement around the waist or raising and lowering of the thighs, improving performance.
