The Leatt MTB Enduro 3. 0 Helmet features a 3-in-1 design that has a configuration for whatever we find ourselves riding. The removable chin bar lets us stay cool on the climb and clip it back on for rowdy downhill, or we can swap in a set of over-the-ear guards to turn it into a 3/4 shell for days when we don't need the extra protection of a full face. In the event of a nasty crash, 360 Turbine Technology helps protect our brains by reducing both peak brain linear and rotational acceleration on impact.
