HK Army KLR SLR Thermal Lens
The KLR PURE Lens System is designed for clearest, most fog-free view of the field. The optical-grade polycarbonate filters UVA, UVB and infrared wavelengths of light, helping to protect your eyes from getting too much direct sunlight in all playing conditions. The dual thermal lens provides a cool barrier of insulating air to eliminate condensation and prevent fogging.
This lens fits HK Army SLR and KLR masks, not the HSTL masks.
