The Explorer XLs thicker frame, sculpted lines, and defined corners give it an edgier, more pronounced style than the standard Explorer. Its fit is optimized for large and medium faces, and for those who prefer to wear larger frames. Constructed of injected-molded TR90NZZ, the Explorer XL provides maximum impact resistance, flexibility, and comfort, and has been tested to MIL PRF 32432 ballistic standards. Like its predecessor the Explorer, the 6-base frames provide all-around protection with a casual look and feel. The Explorer XL is built to excel in demanding environments and is great for activities such as shooting, climbing, and hiking.
