Leatt 4.0 V21.1 Adult MTB Cycling Helmet

Product Information

Don't let overheating slow you down. Leatt full face helmets feature advanced ventilation systems that keep you cool and comfortable, even during intense rides. The strategically placed vents allow for optimal airflow, preventing sweat build-up and ensuring exceptional breathability throughout your ride. Customizable Fit

In its open-face configuration, the Parachute vents reasonably well, offers a decent level of coverage and, thanks to the finely indexed Boa dial that adjusts the retention cradle, delivers a well-tensioned and really comfortable fit. MET was one of the first brands to bring out a convertible helmet, with the original Parachute, but the new MCR (Magnetic Chin bar Release system) is a big departure from its previous lids. For racing true-enduro, where the stages are gnarly and you're a mixture of both scared and excited, I would lean towards the Abus or Leatt. Although I have no intention of proving it, they do just feel so much more reassuring in your hands. Without the creaking and fit issues of the Abus it would be a clear leader, but for long days riding the sheer comfort of the Leatt offsets its slightly hotter running, and I would tie them for first. The Bluegrass isn't too far behind. I personally wouldn't be that excited about racing in either the IXS or the Lazer, whatever the certifications say. Bell was one of the first to market with a convertible helmet, so it’s appropriate that the evolution of that model delivers even greater protection and earned a perfect 10 rating. The helmet in question is the Super DH MIPS, now certified to ASTM 1952 DH full-face standards.You can see an exaggerated version of this with balance bike racing, like at The Malverns Bike Festival this summer. Quite a few 2-4 year old kids have full faces on as their parents want to keep them safe; understandably. When they crash, their little heads whip forwards with the weight of the helmet and they hit the floor every single time when they probably wouldn't in a 250 gram open face kids helmet. Whether you’re chasing split-second advantages in a race or honing your skills on uplift park days, there’s always the risk of a crash. No risk. No Reward. But thanks to the Impact foam of the Gravity 2.0 you have reliable head protection when it all goes a bit wrong. While this core soaks up and dissipates the forces from impacts to your head, the outer polymer shell provides structural strength and structural integrity in a crash. A winning combination. Met’s latest do-it-all helmet certainly isn’t cheap, but quality and finish is top notch and it feels well built, with or without the chinbar. It’s the best looking and functioning Parachute yet, and feels properly sturdy and Alpine-ready in full face mode. Combine this with a good-looking, unobtrusive open-face option, and it’s a very versatile combination.

Bell’s Super DH feels like a full-on downhill full-face (although it’s not quite as solid-feeling as the Giro Switchblade), with firm, rather than plush, padding. The chinbar attaches to the main helmet using magnetic plugs. We found it a bit of a struggle to locate the two with the helmet on, and a bit of a squeeze to get over your head with the chinbar installed. But when combined the whole helmet feels reassuringly solid. We loved the BOA retention adjustment, and it’s great to have MIPs integration to protect against rotational injuries. Overall, the Met Parachute proved to be a well-designed convertible helmet that does everything to a good level. As for looks, I like the modern take on a conventional full face. That said, there is something about the chin bar being so far away from your face and the large visor that does make it appear somewhat bulbous. There is also a decent gap between the edge of the goggles and the helmet. This does help airflow, but doesn't look so hot. It’s comfortable on your head, and venting in its full-face configuration isn’t too bad at all. Andy LloydOne thing to note on the ASTM certification is that it doesn't always equal a safer helmet. There is a lot of noise made around ASTM F1952 and it's great that there are new standards introduced to further qualify helmets for specific riding - however people should definitely be better educated around standards. Performance in both modes is impressive, which means we’d consider it a viable two-in one product, and that goes a long way to take the sting out of the tail when it comes to the price. Leatt’s snap-together convertible MTB 4.0 Enduro helmet is one of only a couple of helmets with full DH certification that can still multitask as a lightweight open face trail lid once the chin guard is removed. And based on our testing, it’s one of the best full face or convertible helmets out there. The Gravity 2.0 also features Leatt’s 360 ̊ Turbine Technology. This tech is focused on reducing the damaging effects of a crash on your brain. It works via 360 ̊moving discs, all made from an energy-absorbing material. These impart a reduction of rotational acceleration to the head and brain by up to 40%. The system also improves the absorption of impact energy - it reduces peak brain acceleration by up to 30% at the impact speeds associated with concussion.

Johan Hjord - Age: 48 // Years Riding MTB: 16 // Weight: 190-pounds (87-kg) // Height: 6'0" (1.84m)On the trail, we found the Enduro 4.0 very comfortable and stable in action – especially with the chin bar on. The chin bar sits very far from the face, which makes the helmet very breathable even in full-face mode. Despite the goggle strap partially covering a number of vents when placed in the most natural position, the overall level of ventilation is still very high – certainly one to consider for warmer climates or if you want a helmet that you can use in full face mode most of the time. All of the helmets featured here are worthy options if you're in the market for a lightweight full-face, but choosing the best one will depend on what type of riding you're planning on using it for. In full face mode I felt that the Leatt MTB 4.0 Helmet more closely resembled a ‘normal’ full face helmet in terms of the way it looks and fits with the snug cheek pads and solid construction. When I put it on, I felt like I had a full on DH helmet, albeit with a bit better ventilation, and when I wear a helmet like this it gives me a bit more confidence to send it.
