When it comes to enduro-style full faces or pedal friendly full-face helmets, it seems there is a split in the products offered. Some brands seem to be taking their lightweight, well ventilated trail lids and add a chin bar while others work from a DH helmet starting point and remove material and increase ventilation. We believe that both styles of helmets have a space in the market depending on the type of rider and terrain.
We’d say that the Leatt DBX 4.0 more closely resembles Leatt’s downhill helmets, but in our opinion looks better. The chin bar and other areas of the helmet see a lot more ventilation and help the helmet breathe better than a full-blown DH helmet without leaving us feeling like a face plant would snap the chin bar. Drew doesn’t always fit Leatt helmets well with his 56cm head but found the DBX 4.0 to be one of the most comfortable helmets he’s ridden in. Sourpatch wore the size medium and felt that it was a comfortable and safe feeling fit.
The large vents over the brow help push air through the top of the helmet once you get moving over about 7mph. The exhaust vents do a decent job of allowing hot air to escape out the back of the helmet, but we’ve never heard anyone say they wouldn’t like a cooler helmet. Obviously the more solid construction is also part of what makes this helmet look so good and feel so protective compared to others like the Kali Invader. Not to knock that helmet as it’s a very safe and protective unit, just has a different user and application. The chin bar and mouthpiece on the Leatt helmet are open and breathe quite well, allowing us to hydrate easily or take in deep breaths on long climbs or sprints.
