Lifeguards have a demanding job that requires them to be on constant alert. They must be ready to rescue swimmers who are in trouble, and they need to be able to spot potential hazards quickly. In order to do their job effectively, lifeguards need to wear clothing that will protect them from the sun and the elements. Straw hats are a popular choice for lifeguards because they provide excellent sun coverage. The wide brim helps to shield the face and neck from harmful UV rays, and the straw material helps to keep the head cool.
