Even if you are wearing functional clothing that makes you feel cool, the effect is diminished if you wear a floating vest surrounded by thick buoyancy. To overcome this dilemma, the Act Game Vest incorporates a mechanism to increase breathability.
The back lining, which has a large contact surface, is made of mesh fabric to improve breathability, and the side holes and the structure that allows air to be taken in through the armpits and released through the shoulders create air passages throughout the entire vest. Furthermore, by combining this with Shimano's patented technology of creating air holes in the buoyancy body, heat is no longer trapped inside the vest itself.
