But do they use the commercial sea float foam in helmets? There are thousands of different formulations of foams out there. Everything from a styrofoam cup, cheap foam coolers to insulation used in freezers or buildings. If the manufacturer suggests replacing something after a certain date, I would hope they know what they are talking about. Making many items UV stable adds to the cost. I am sure they could make a bike helmet that would last 100 years, but if they did they would kill their market and the price would be prohibitive.
