The Transtec Tactical Optical System includes everything one would expect from tactical goggles in a single package. The anti-scratch and anti-fog lenses ensure clear and unobstructed vision at all times. One of the best features of this system is that it comes with interchangeable lenses one of which is smoke and the other is yellow colored. The sturdy black frame comes with elastic that can be detached from the temple area. Foam padding on the insides plays a vital role in providing comfort and a great fit in all mobile conditions. Again, the UV 400 protection also provides added protection from harsh sunlight and ultraviolet rays.
