Karate Fighter GI GAKUSEI is the perfect choice for beginners. In heavily used areas, such as the lapels or the hem on the arms and legs, the Gi is particularly robust. Children love to move and a Gi gives them the freedom they need. The kimono is made of mixed fabrics and it owes its excellent properties to technology and to the natural strength of cotton. It weighs less when it is compared to the Kata-Gi.
