We  only sell Visors that carry CSA certification.  Our visor selection includes only visors for use by referees. Beware of non-certified products.  HECC certification is not sufficient for use in Canada.  
We stock entry level through Pro quality visors both permanent models and models with replaceable lenses.  Of course we stock the replacement lenses as well, sold as a pair or individually.  We strongly suggest protecting your visor investment with an optional visor cover.
