Leatt MTB 3.0 helmet review

I still remember getting a Columbia 3-in-1 jacket for Christmas one year and thinking it was the coolest thing ever. Three jackets in one? Now that's the future. You could wear just the outer shell, just the inner liner jacket, or zip both layers together to create what I thought was the height of fashion at the time. Of course, I also thought that khaki cargo pants and braided leather belts were the bee's knees, so make of that what you will.

Decades later, it turns out the 3-in-1 concept still exists, this time in the form of Leatt's MTB Enduro 3.0 helmet. There have been full face helmets with removable chin bars for years, but the Enduro 3.0 adds another option into the mix – it can be worn as a full face helmet, a ¾ helmet, or a half shell depending on how it's set up.

Swapping out the various pieces is as easy as pushing a button on the side of the helmet and then disengaging the metal tab that secures the chin bar or ear flaps near the temples. It's a quick procedure, and there's a distinct 'click' when a piece snaps into place. The size of the chin bar when it's detached means this isn't the sort of helmet that you would switch modes on mid-ride, unless you like carrying an awkward-shaped chin bar around until it's time to go downhill.

The ratcheting dial at the back of the helmet was a little tricky to loosen with one hand.

Leatt's 360 Turbine system is designed to help reduce rotational impact forces.

Along with the EPS foam liner, the MTB Enduro 3.0 uses Leatt's 360 Turbine Technology, which consists of 8 disc (or turbine) shaped pieces of energy-absorbing foam. Those turbines are intended to help dissipate rotational impact forces that occur during a crash.

The helmet is secured with a magnetic FidLock buckle, and a ratcheting dial is located at the rear of the helmet to fine-tune the fit. That fit system has 3 different vertical positions, although I found it had a tendency to slip out of place – more on that in a bit. The $260 Enduro 3.0 is available in sizes S to L to accommodate head diameters between 51 - 63cm, and there are four different color options.

A spring-loaded push button system is used to secure either the chin bar or the ear flaps in conjunction with a metal tab that slots in near the temple area of the helmet.


Fit & Performance

I tested a size medium helmet, the size I typically wear for my 57.5 cm, ovalish head, and found the Enduro 3.0 to be very comfortable. The padding is nice and thick, and there weren't any pressure points in any of the configurations. The feel of the helmet is a little different in each of the three modes, so I'll break it down a little further here.


Leatt MTB 3.0 helmet review

Half Shell:

This is the configuration I used the least, in part because of how silly I thought the long visor looked. That's obviously a fashion over function thing, but there are lots of helmets on the market that look a lot less goofy, at least in my opinion. It's also on the heavier side for a half shell helmet – the 473 gram weight is at around 100 grams higher than most other dedicated trail-oriented half shell helmets. Sunglasses will slot nicely into the vents at the back of the helmet, and I never had any issues with them slipping out of place.

In half shell mode I'd put the MTB 3.0 in the middle of the road when it comes to ventilation. It's not uncomfortably hot, but it's also not mind-blowingly light and airy. Overall, if I was evaluating this helmet solely as a half shell, I'd give it a C+. It's totally adequate, but there are lighter options with better ventilation and retention systems. However, the fact that there are still two more configurations shouldn't be overlooked.

3/4 Mode: This ended up being my favorite option, especially on cooler fall rides. The extra side coverage kept my ears a little warmer, and I could still hear what was going on around me thanks to the positioning of the cutout on each side panel. The helmet feels more balanced and stable in this orientation too; the side panels give it more support, so it feels less top-heavy than it does as a half shell.

Compared the the recently released Fox Dropframe, which is a dedicated 3/4 helmet, the Leatt is a little lighter (22 grams), has slightly better ventilation, and doesn't block outside noises as much. The Dropframe does have a more solid, substantial feel, though, and a better fit system.

Leatt MTB 3.0 helmet review

Full Face Mode: The comfortable fit of the Enduro 3.0 continued in the full face mode, except for one thing – the fit adjustment system would move to a different vertical position when I tipped my head back; this was especially noticeable in steep terrain. I'd drop in, and then it wouldn't be long before I'd hear the 'click, click' of it shifting to the highest position. I should also mention that the ratcheting fit adjust dial is easy to use to tighten the helmet, but very hard to turn in the other direction to loosen things up. According to Leatt, the issue with the dial occurred with the first production batch and has since been corrected, so it's worth trying on the helmet and giving it a try before purchase if posssible.

The helmet's 857 gram weight is in line with other more pedal-friendly full face helmets. I didn't run into any issues with goggle compatibility, and the Turbine system was nice and quiet, a welcome change from the creaking and squeaking that occurs with certain Mips systems.




Pros

+ Space saving option for traveling
+ Comfortable and quiet in all configurations
+ Saves money over buying three individual helmets


Cons

- Visor looks comically long in half shell mode
- Retention system is hard to loosen, can change vertical positions too easily




Pinkbike's Take
bigquotesGetting a 3-in-1 concept right is tricky - there's a high probability that the result will end up in the jack of all trades, master of none category, and that's the case with Leatt's MTB Enduro 3.0. Each configuration works as intended, it's just it's not the best helmet available for any of those configurations. Still, for riders that regularly find themselves on road trips or vacations where it'd make sense to wear a half shell helmet one day and a full face the next, this could be a great alternative to bringing two or even three different helmets.

 This helmet did its job when I broke myself in Oct. a broken collar bone, 5 ribs and rash all over but the helmet took one for the team at the right temple area. Crushed. CT scan negative for any head injury and surprisingly no concussion symptoms. Leatt’s crash replacement program is also tops.

Gotta disagree with the Con of too long of a visor/peak. Grateful for it in the morning and late afternoon. Also the retention knob resistance goes down over time.

 Only 3 modes? What about when I need a TT helmet on my vacation where I also need a half shell a 3/4 and then the chin bar? Also where is the corkscrew and bottle opener and nail trimmer? Not enough features /s

 The 3/4 version makes sense in cold climates.
Otherwise I honestly do not see the point of it… go full half shell or chin bar on…

 3/4 provides more surface area for a side impact compared to half shell, dissipating energy over more crushable foam.

 @Loche: Well.. The times I crashed with a half shell when I should have been wearing a full face it was really chin damage… the side protection would have been redundant.

 Since about 5 years, I am riding 3/4 / Openface helmets, when not in a bikepark.
Main Reason: I feel more safe,
Second reason, the fit is simply better, helmet stays put with less movement even in very rough terrain.

It started for me with a Giro Switchblade (never using the chinbar), because I wanted a non-Fullface, but with ASTM / DH Certification.
Then then used the Giro tyrant, because way more slimline / less bulky / lighter.
Since end of last year, I use the 3.0 Leatt (only in 3/4) mode, because it is the best of both worlds: Slimline & Astm certified.

About Heatmanagement: the Sitchblade was quite hot,
Tyrant and 3.0 were all fine for me, even in mid summer, no huge difference to half shell helmets.

If I wear fullfaces, I wear non convertable ones.

 @heyj: Agreed… the 3/4 setup is really just stupid.

 @SchalkMarais, like you mentioned, it's great in the fall / winter for a little extra warmth. The Leatt does a good job of not being too hot; it's the wind blocking that helps when it's chilly. 3/4 helmets also work (and look) a lot better with goggles than a half shell would.

 @mikekazimer: We rarely have the need for the extra warmth down south in SA.
I have an older Enduro convertible. Not perfect, but great to have the option to switch to full protection with virtually na hassle…

 I had a crash in a half shell Fox helmet years ago, the helmet twisted sideways slightly and I got a huge cut on the side of my head, ending a few millimetres from my eye. Two hours of plastic surgery and a decent scar. After that I went to removable chin guard helmet, it was a pain taking it on and off. Got a Fox drop frame a few years ago and won’t go back, more coverage and stops any helmet twisting, very good solution for people who know what it’s like to take a big crash to your face!

 3/4 is great for when you crash on your side, so super good for jumps and stuff. Saved me more times than I can count with learning 360s.

 I picked up a TLD Stage lightweight full-face for the relatively tame bike park riding I do. It ended up being so light and comfortable that I don’t really have an excuse not to wear it on trail rides when it’s 70 F outside. I do not notice it while riding. Drinking is annoying, and some older guys in the parking lot clearly roll their eyes at me, but I’d feel stupid if I f*cked my teeth up because I chose the half-shell for style points. I’m already riding a hardtail, no one thinks I’m cool anyway.

 I got myself one for this year. Really comfy, and the different configurations are nice for the odd time I can make a trip to bike parks. The visor doesn't seem replaceable tho. It has fragile push tabs instead of bolts or even just better designed tabs. Idk, haven't contacted Leatt about it yet
  • 3 0
 The visor is designed to break away in a crash. That's why it doesn't have bolts. hopefully the visor doesn't actually break and can be reattached. Of course, its possible that if the impact breaks the visor off, the helmet may be done anyway. Just speculating here.

 @jojotherider1977: makes sense for warranty and crash reasons, but mine's only been stressed from a helmet mounted light.

I had a MET helmet that had 2mm or 2.5mm screws for adjusting the visor, nothing heavy duty. It was handy for mounting my light.

 Having a visor that can break away in a crash but it also easily replaceable or reattachable seems like it'd be the leatt they could do.

 After owning a Gravity 4.0 for a year and a half, I got a concussion (not the helmets fault bike landed on my head). i loved the helmet enough to get another Leatt...but this time I got the 8.0 DH helmet. The minimal extra weight is worth the added peace of mind for me. I haven't felt too warm in it yet, even when pedaling uphill.
  • 5 1
 Is it just me or does anyone else think that 3/4 helmets look ridiculous? I mean I get why they exist, and do offer safety improvements over half shell, but I just can't get over the look. I guess open shell motorcycle helmets are popular with the hipster crowd.

A helmet adjustment that slips just while riding is an automatic fail in my opinion, to the point that it should be subject to a recall.

 A year ago I agreed, now they are starting to grow on me, still not getting one... (yet)

 I have this helmet and am pretty happy with it. For any ride where you pedal up to strictly go down stuff that is even kinda hard, I don't know why you'd want to deny your face protection. I can't rationalize an exposed face unless you are pedalling the entire time (flat lands), because at that point, yeah, it's harder to breathe. But if you ride up and down mountains, strapping the chin guard on and putting it on at the top is a really nice option. My only grip is the helmet kinda hits my ears a bit, but otherwise works well in both XC and Endurobroguy mode.
  • 3 0
 I’d rather buy two 2022/23 sale helmets for a similar price. I already bought a Poc Tectal for £30 because my head is the size of a pea. There’s plenty of full face helmets available if I need one for under £200 and (in my opinion) they look a lot less goofy.
  • 2 0
 I have first bought the 3.0 over the 4.0… felt cramped and sitting on the top of my head. And the locking system was very bad, cumbersome. Bought the 4.0. Fits great, feels almost like a full face. Seems to be much more sturdy and well built. Goggles fit is also good. I sweat a LOT, and the liner is great. You get 2 liners so it is easy to wash. Half helmet is also very comfortable, while bigger than dedicated 1/2. Only downside for me, Visor is flimsy and will probably brake sooner than later, just by carrying around the helmet! And I also find that Leatt sizes run large… I normally wear L in a lot of brand, but have to go M with Leatt.

 "The size of the chin bar when it's detached means this isn't the sort of helmet that you would switch modes on mid-ride, unless you like carrying an awkward-shaped chin bar around until it's time to go downhill."

You got an example of a 1/2-to-full helmet that does fit this bill? This chin bar seems to be no bigger than any others that convert a half-shell, and definitely smaller than the few that are secured by wrapping all the way around the back such as Bell Super 2R/3R.

(Yes, there is at least one (Uvex Revolt) 3/4-to-full helmet with a smaller removed chin bar, but that's not what this is.)
  • 4 2
 The Giro Switchblade's detachable chin bar is the smallest that I'm aware of. In any case, switching from half to full-shell mode always seems like it's more hassle than it's worth to me.
  • 3 0
 @mikekazimer: I think for peak summer hot weather Enduro racing the removable chin guard is nice. If you're going to be pedaling for a while then the few minutes to remove it and put it on your bag is no biggie. Especially if you're taking a moment to catch your breather after the descent/climb. Maybe I need to just suck it up though and stay full shell the whole time!

 @mikekazimer: Switchblade is a 3/4-shell at its smallest, of course its chin bar is smaller. Did you miss the part where I mentioned that 3/4-to-full conversion doesn't count for this comparison?

This helmet's chin bar takes it from 1/2 to full, and it's the same basic size, or smaller, than any other chin bar that does the same.

 I’ve been running one since it came out.
I never use it half face, and the big visor stops it looking goofy as a full face. 3/4 is great for dirt jumps and skate park and then as a pedal friendly full face with the chin bar. It’s definitely no full dh helmet and I still use a proper full face for anything I don’t need to pedal up and racing.

 Leatt makes a great product, they also do all their own testing and design their own products. The only issue I had with their helmets is that my sweaty head wore out the rubber pinwheels (turbines) too quickly.

 The mandible/chin-bar is easily strapped to my camelbak, doesn't move around at all. It's easy to switch to full face for the DH midride. Camelbacks aren't fashionable anymore but whatever.

 I don't know if I missed something, but I got one and returned it as it was pretty much impossible to put on and remove with the chin bar on.
Are you supposed to mount the chin bar only when the helmet is already on your head ? Cuz' if so there was no way my head would go through with the chin bar. The strap would almost scratch the sides of my head when trying to do so.
Too bad as I really liked the 3.0, it has a long visor but at elast it protects well from the sun, I can't say the same about my new one, a Fox Speedframe who's visor is too short IMO and can't be adjusted.

 Not to be a pedant, but: "Swapping out the various pieces is as easy as pushing a button on the side of the helmet and then disengaging the medal tab that secures the chin bar or ear flaps near the temples".

I think "medal" should be "metal"? Talk-to-text and spellcheck still lets those homonyms slip through! Smile

 That's definitely an option, but on long technical climbs, it's pretty nice not having a full face dangling from your backpack or anywhere else. My crappy backpack can't handle a helmet, but it sure is nice riding without a sweatcan on your lid.
