Design inspired by the Royal Air Force's pilot vest

The velcro closure side opening allows the size to be adjusted to taste

The poly-blend fabric has a matte finish and is anti-pilling

The special four layer structure has insert yarns arranged in knit fabric, bonded into a bag-like shape - giving it volume

It also has moderate heat retention and comfortable stretchability

The inner side uses polyester spun yarn for a comfortable feel and moderate absorbency
