Made with Cotton, the Simple Stitch work cap will absorb sweat away from the skin and can be worn for long periods of time without feeling uncomfortable. The material has been reinforced to protect your head from harmful UV rays, and the 5.5cm (2.1inch) deep brim will keep the sun out of your eyes too! Although the hat is advertised as a summer hat, it is well suited to all seasons as Cotton is a very seasonally flexible material. Known to cool you down the warmer months and absorb moisture, Cotton also keeps your head warm during the cooler months as well. This hat is also made from Polyurethane, known to be a long last material which can last in high stress environments. It outperforms most materials against abrasions and heat, so a great hat for those in rough conditions.
