The Breathable Sou'wester has been a staple in the MUSTO collection for generations, providing protection for day sailors. Waterproof and breathable, the fully taped seam construction with added durable water repellent (DWR) treatment gives you complete protection in the rain. The ergonomically shaped brim scooped around the neck protects you against the sun when exposed to the elements. The drawstring adjustment under your chin helps secure the hat during windy weather.
