The bulk of the Yachting cap is made from strong, 100% cotton twill material, with a sweat-resistant hem & reinforcing sewn around the inside. The brims are plastic (not cardboard), & covered in soft fawn-coloured suedette on top with navy covered twill beneath (to reduce glare on the eyes). The size-adjusting strap has a metal buckle, & metal sleeve for tucking away the end neatly. This cap is heavily embroidered with the word ` Crew` in cotton thread.
