Viva la resistance! The Resistance 300 Face Mask from CCM comes with thin flat wires and utilizes a straight bar design to enhance visibility. The multi-density, antimicrobial fabric covering on the chin cup allows maximum comfort with an antimicrobial treatment. Hardware on the helmet, such as the top clip, provides a unique shock-absorbing design. The J-clips are easy to adjust without removing the screws. Just loosen and adjust to fit.
