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.

Originally bought size L, as it starts at 23.3 in and I have a 24in headband... thing was massive, even tightened all the way it wouldnt fit. Since exchanging for a medium, fits much better. It is still a pretty thick helmet, better for more aggressive riders as its probably a bit much for most riders. Airflow is decent considering how large it is. Not crashed in it but seems to provide a lot of protection, and the bigger lining is comfortable.

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!
