Why We Like The MTB 4.0 Enduro Helmet

We trust Leatt to provide quality protection and coverage for our enduro and mountain bike rides, and that includes the MTB 4.0 Enduro Helmet. It's known for its ventilation and comfort, and it's the helmet we're grabbing before heading for an enduro ride or a trip to the bikepark. It's fitted with 360 Turbine technology which both lowers the cost and manages protection, and its full-face design still offers breathability. The MTB 4.0 Enduro Helmet reduces rotational acceleration and absorbs energy upon impact to better protect our heads from injury. We know we're covered if we crash with the MTB 4.0 Enduro Helmet.

  • Full coverage helmet that offers protection and ventilation
  • Lightweight polymer compound shell in two sizes
  • Breathability from 22 total vents across the helmet
  • Removable mouthpiece ventilation cover
  • Optimal neck brace compatibility for ease and comfort
  • Dri-Lex moisture-wicking, anti-odor, washable internal liner
  • Removable chin bar with easy-fit Stainless attachment system

How to Measure:
Measure the circumference of your head with a tape measure. Place the tape measure slightly above the ear and bring it across the mid forehead completely circling the head about 1 inch above the eyebrows. Take several measurements to make sure you have the largest size. If you do not have a tape measure, use a string and measure it against a ruler.

Great Helmet

This is a great helmet, but the sunglass dock doesn't work at all. The glasses just slide out of it, but the rest of the helmet works flawlessly. Don't know how I feel about the 360 Turbine yet, but from what I see I think it'll work great.


Does it have Removable chin bar?
