Lightning X Products has been making quality public safety bags for nearly 25 years. From time to time we get the urge to improve upon existing bag designs. The LXFB45M uses Quad-Vent Technology that features four uniquely shaped mesh vents located at each corner of the turnout gear compartment to promote cross ventilation. This keeps your gear fresh and helps prevent mildew from forming. Our competitors only offer a bag with one vent, in the rear of the bag…how is air supposed to flow through just one vent? The Quad-Vent bag is large enough to hold all of your gear, boots and helmet comfortably – without being so big that it becomes cumbersome to carry around.?
