2021 Leatt AllMtn 4.0 MTB Helmet

The Leatt AllMtn 4.0 mountain bike helmet is an amazing choice for safety-conscious riders who don’t mind a little bit of flair to go along with their safety. The AllMtn 4.0 helmet is a pretty cool and futuristic-looking helmet that not only looks great, but saves brains as well. This helmet is the total package, and it makes a lot of sense to have all of these attributes rolled into one, as it just makes it easier to find the right helmet that you look forward to wearing as opposed to just doing it because you should. The 4.0 features 13 vents and is made from a lightweight polymer compound, so it’s quite light and cool on your head—it feels like there’s not much there, but when you need it, technologies like their 360-degree Turbine tech makes the rotational bran acceleration decrease by up to 40%, so these are real-world safety numbers that we’re dealing with. Thanks to Leatt’s commitment to safety and style, you’ll love the AllMtn 4.0 mountain bike helmet.
