Why We Like The MTB 4.0 Enduro Helmet

We trust Leatt to provide quality protection and coverage for our enduro and mountain bike rides, and that includes the MTB 4.0 Enduro Helmet. It's known for its ventilation and comfort, and it's the helmet we're grabbing before heading for an enduro ride or a trip to the bikepark. It's fitted with 360 Turbine technology which both lowers the cost and manages protection, and its full-face design still offers breathability. The MTB 4.0 Enduro Helmet reduces rotational acceleration and absorbs energy upon impact to better protect our heads. We know we're covered if we crash with the MTB 4.0 Enduro Helmet.

Great convertable helmet

I've used it several times
Size Bought:

The Leatt 4.0 Enduro helmet feels very comfortable in half-shell configuration. This is great for most trail rides and for climbing. With the chin bar on it feels almost as protective as my DH helmet. This helmet is great for long climbs with fast technical descents. I really like the added protection and have no issues with weight or comfort. The only issue I've found is that snapping on the chin bar can be finicky.

Great Helmet

I've used it once or twice and have initial impressions
Size Bought:
5' 8"

This is a great helmet, but the sunglass dock doesn't work at all. The glasses just slide out of it, but the rest of the helmet works flawlessly. Don't know how I feel about the 360 Turbine yet, but from what I see I think it'll work great.
