Review: Incredible helmet at twice the price - I've owned a few helmets in the 15 or so years I've been riding, none of them top-shelf, some cheap, but most around the $300 price point. Then I got this helmet... the styling, features, build quality, materials and fit are on par with anything I've had that costs 3x or more. First, the technicals. I'm a medium in most brands, intermediate oval (given the choice), and prefer the way SHOEI fits over Arai. This LS2 fits as good as any I've had in the past. Nice and snug, no slop when I shake my head, my ears don't bend in half when I put the helmet on, and no noticeable pain points after a decent ride. I bought it in white, the pictures show the decals as black and red, but there is no red on the helmet I received. That aside, the quality is impressive, you can find plenty of YouTube reviews for details but the gist is that nothing about this helmet feels "cheap". Now the style. Sure it's subjective, but this thing looks badass. Most helmets are either obnoxiously aggressive or look like something grandpa wears on his two-wheeled RV. This helmet strikes a balance between the two, confident without being annoying, aside from the four "LS2" logos begging for attention from every angle. The only gripe I have with this helmet is the lack of a detent on the clear visor between fully closed and fully open. I'm used to having an extra "click" that keeps the shield open just a crack to allow for extra ventilation on hot days. But the integrated sun visor makes this more of a nit-pick than anything.
Review: Great choice - Great looking helmet. According to the chart I was a 54” but ordered up to a medium. Head fits great. Padding on the cheeks are tight and squish my face but was told move it around some and it will relax over time. Was going to send it back for a large but kept and worked with the cheek foam. Fits good and has indents to mount helmet speakers in. I went with the Lexington G2P. Sounds great and fit perfect. The drop down lenses work great in the sun. Not quite sure yet on the air flow as it was 91 outside and my head was a little sweaty after riding 3 hours.

### ⭐⭐⭐⭐⭐ Incredible helmet at twice the price
*by I***N on July 31, 2017*

### ⭐⭐⭐⭐⭐ Gorgeous helmet, but pretty round.
*by M***Y on May 30, 2024*

This helmet is stunning. It feels super well built. The speaker cut outs are in kind of a weird spot, but they fit my 45mm JBL Cardo speakers well enough. The drop down visor is fine, but doesn't really matter to me as I have prescription glasses with transitions. The main visor is either open or close, there is no in between. That's strange. Unfortunately, this helmet didn't fit my head. The chin guard is too far inward and while it was a beautiful quilt to it, it also rubbed against my chin. Most helmets rub my chin a little, especially while talking, but this one was rough. The chin guard also sat too high up and exposed my chin. The chin strap is a quick release and is fantastic. Every helmet should be this way. I didn't get to ride with this helmet to test wind noise or vent usefulness, but it looks made well so I'm sure it was fine. Beautiful helmet that unfortunately just didn't work with my more long-oval head.
