Due to the specification of hooking the thumb, it is a gentle UV cover from the top of the elbow to the back of the hand. Organic cotton yarn dyed with ceramic charcoal was mainly used. Ceramic charcoal contains a well-balanced amount of minerals such as carbon, silicon, and alumina, and has a shielding rate of 94%. (* UV shielding rate measured by the Boken Quality Evaluation Organization) (* The UV shielding rate is 94% in the gray area.) ） We have taken into consideration the thinness as much as possible so that it can be worn comfortably even in the hot summer months. It is an item that can provide UV care from the back of the hand to the arm while maintaining the gentleness of organic cotton. The hole for the thumb is also sewn in.
