Why We Like The MTB 4.0 AllMtn Helmet
Brush up on your history of Leatt, and you'll discover a rich past based upon the creation of safer, smarter equipment for those that ride off-road. The California-based brand's two decades of experience has provided us with reliable gear from body armor to neck braces, and the MTB 4.0 AllMtn Helmet is their latest launch to offer superior protection at an affordable price. Its rugged frame is built from a lightweight polymer compound to reduce neck fatigue as you grind up the mountain, and EPS foam handles higher speed impacts no matter where the trail takes you. We especially like Leatt's 360-degree Turbine Technology, which dramatically reduces harmful rotational and low-G impact forces.
- Rugged helmet tackles trail rides and enduro
- 360° Turbines guard against low-speed and rotational impacts
- Polymer shell pairs with EPS foam to absorb greater impacts
- Dri-Lex liner wicks moisture to promote breathability
- Fidlock magnetic buckle for easy entry and exit

Extremely Disappointing

Upgraded from a 3.0 to this and couldn't be more disappointed. The retention dial broke and fell apart after just a handful of rides rendering the helmet completely useless. I purchased the helmet early in the year and didn't get to ride much due to the very wet spring in Colorado this year. Unfortunately, that means that the helmet was past the 30 day return window for Backcountry when it failed. Hopefully Backcountry will do the right thing and resolve this equipment failure.

Bought the 3.0 and this one (4.0). The quality and fit seemed very good for this range of MTB helmets. Adjustment was easy and fit was very good. Returning because it is a bit heavier than the 3.0 and was more protection than I probably need doing slower, technical riding. These helmets (Leatt) appear to fit more oval-shaped domes. Wasn't overly impressed by the eyeware on-board storage but I also didn't try very hard to make my Smith Longfins attach easily.

This thing is massive! Very nice looking, but way too huge! Sticks off the head more than any helmet I have owned. I was super disappointed in how grande this helmet fit because of how awesome it looks. I wanted to keep it, but I knew my riding buddies would ridicule me with endless Space Balls jokes... It's that big!

Contact Leatt. They’ll likely warranty it and will directly contact Backcountry if needed.
