Bunker Mentality are a company that puts performance & style at the heart of everything they do. They want golfers to be comfortable to wear their products both on & off the golf course & the new Kai Gilet fits the bill. The vest uses Clo Insulation wadding technology, a highly breathable insulation quilted front & back, which helps to maintain the body temperature even on cold winter's days. This also allows moisture to be moved away from the body keeping you comfortable throughout your round.
