When specifying our yachting caps, we chose the "top-spec" Options All the way. So the bulk of the yachting cap is made from strong, 100% cotton twill material, with a sweat-resistant hem and Reinforcing sewn around the inside. The brims are plastic (Not cardboard), and covered in soft fawn-coloured sedate on top with Navy covered twill beneath (to reduce glare on the eyes). The size-adjusting strap has a metal buckle, and metal sleeve for tucking away The end neatly. Each yachting cap is heavily embroidered with a crew position in cotton thread. The quality is excellent As is The price. Great offer! Save GBP6 when you buy any four yachting caps.
