The LT Series structural fire helmet is the result of 20 years of Bullard engineered polymers technology and expertise. Featuring a streamlined design, low center of gravity and increased headroom for more comfort, LT Series helmets incorporate recommendations from leading veteran fire fighting professionals. Recently re-engineered, the LTX helmet is the most comfortable low profile helmet on the market. That makes Scotchlite the toughest material available for helmet markings.
