Tested : Pete’s Leatt MTB 4.0 Helmet Review.

Leatt’s current top-of-the-line half face enduro MTB helmet ticks all the boxes but does it pass the test when out on the trail?

Pete casts his verdict on the big orange crash hat from South African protection specialists Leatt.

On the face of it, Leatt’s MTB 4.0 helmet has everything going for it. A polycarbonate shell mated to an EPS/EP0 liner, rotational impact reduction system, breakaway visor, sunglasses port, Fidlock closure, lots of vents, low weight and all the relative certifications. At £179.99 it’s not astronomical for a top-tier MTB half face either.

Leatt brings it’s own rotational impact system in the form of the 360 Turbine Technology that are small blue discs that sit inside the helmet, with a claimed 30% reduction in peak brain acceleration and 40% reduction in brain rotational acceleration. All this is designed to reduce that second spike of impact with the head and brain, the first impact you can deal with by not falling on your head…

On my rather sizeable loaf, the inner cradle seems to sit higher compared to something like the Fox ProFrame, but the adjustment dial has plenty of clicks to help fine tune and it’s certainly not uncomfortable by any means. The large shell has plenty over the rear of the head and you feel well-protected in this thing.

Out on the trail you soon forget about the helmet being on your head, the visor sitting high enough to be out of your eyeline without you looking like a greenhorn. Ventilation is excellent without being chilly on those winter days.

Thankfully I haven’t had to test the safety features of this helmet but I am confident it’s up to the task. I just hope I don’t have to test it’s ground interface skills.

What do we think?

Leatt have, in the MTB 4.0 helmet created a lid that covers all the bases, without any weird fit issues, simply a helmet that is well-priced for the features and ticks all the boxes for anyone after something to protect their head with.

We love:

  • Feature-packed
  • Light weight
  • Well-ventilated
  • All-day comfort

Could do better:

  • Not an awful lot
