The front and back feature the insulated quilting to keep your body warm while out playing which helps keeps your muscles relaxed for turning throughout your swing. This quilting is filled with Clo insulations Teknica range which uses an i-fibre construction for warmth and breathability as your body heat gets trapped in between the fibres and keeps it close to your body. The Teknica range is also incredibly soft to touch and quiet so you won’t be distracted during your swing. Like with any golf gilet the Kai has been designed to protect your body from the wind while keeping it warm so your arms can swing freely. The shoulders and side are made from brushed material for maximum comfort and mobility so you are not restricted while playing. The Bunker Mentality brand name is featured on the silicone shield on the left chest.
