Game vest equipped with the BOA Fit System for size adjustment, easy on/off, and ventilation. This game vest features the BOA Fit System for enhanced ease of use and a better fit. It also includes a ventilation function, which is welcome in hot weather. ■ Excellent ventilation structure for comfortable fishing in spring and summer Even if you're wearing functional, cool clothing, it's less effective if you're wearing a thick life jacket. To overcome this dilemma, the Act Game Vest incorporates a mechanism to enhance breathability. The lining on the back, which has a large contact surface, is made of mesh fabric to improve ventilation. In addition, by adopting a structure that allows air to enter from the side holes and armpits and exit from the shoulders, an air passage is built throughout the vest. Furthermore, by incorporating Shimano's patented technology of providing air holes in the buoyancy material, the vest itself no longer traps heat. ■ Act Concept Buoyancy Design Buoyancy material design analyzed from an angler's movements from an ergonomic perspective. By dividing the front buoyancy material into seven sections on both the left and right sides and varying the thickness, the protrusion on the front is reduced. ■ Abundant pockets, eliminating the need for a bag
