  • Impact energy management epp-lo speed / eps-hi speed - patent pending safety system that combines epp (low density impact foam for low speed energy management) co-molded with an eps layer (high density impact foam for high speed energy management)
  • B-series mips rotational brain protection system - mips b-series solution allows the tld fit system to attach directly to the mips lfl (low friction layer) vs other models where the fit system is anchored in a stationary position to the sides of the helmet. This solution creates an optimal 360 degree fit for a helmet that fits perfectly and can maximize the safety features built into the helmet
  • 3-way magnajust® visor with goggle stowage - patent pending magnetic adjust visor system, allowing you to easily stow your goggles on the upswing and upon putting your goggles back on your face-the visor will automatically click back into position via the magnajust system or easily adjust to lower positions via the 3 way point of engagement
  • Tld sweat glide system - carefully designed eva wicking foam that is installed via adhesive backing, behind the comfort liner along the front brow, directing sweat away from the eyes and optics. Helmet ships with this installed and an additional (2) spares are included
  • Tld micro adjust 360° fit system - all new retention stabilizer for custom tuned fit. Full 360 degree fit where the retention arms are integated fully into the mips® system.

  • 2 piece ionic® comfort liner - ionic® liner for anti-microbial & sweat wicking properties that is also quick to dry. The liner has precision cut lines for those who want to customize the fit of the helmet to reduce the amount of comfort liner for certain head types-this custom tuning can aid in ventilation and comfort
  • 16 optimized vents maximum airflow - 16 vents optimally tuned with the channeling of the helmet to create the most intake and exhaust of any half shell helmet we've produced
  • Advanced layering 3 piece shell - 3 piece shell layup not only adds to the technical refinement aestethic, it allows the helmet to have more design graphic design options and allows seperate parts of the epp/eps to be laid in during construction
  • Composite smart-shear screws w/anodized washers - composite screws are made to shear during a severe impact / direct hit to the visor
