Bought my first bike this year, a Harley - went for style over function and bought a half helm from the Harley store to go with it. $300 later, the chin strap attachment I had to get (I sucked at the ring-tying) sucks hard - I'm getting bugs lodged in my ears (I ride a lot in country fields), and I'm clinically deaf from the wind after a short 45-minute ride. Sizing Chart: The sizing chart is pretty accurate, I have a big head (lot of hot air in there I guess) and where I thought going a size up was going to be roomy it's actually quite snug but still comfortable. Chin Strap: Kicks the crap out of both the default ring on the Harley helmet as well as the additional clip I had to buy. You "un-snap" your chin strap similar to Ski boots...just lift and pull. Where the Harley Helmet moves a bunch when I'm over 50 mph, this helm stays put. Padding: Extremely comfortable - the snug fit makes it kinda tricky putting my glasses on after I put the helmet on, with an upside that the padding holds my glasses in place so there's no "nose sliding" as I look around. The padding is a little bit tight on my ears - but this helps for a more quiet ride. Visors: Clear visor is indeed super easy to remove. Tinted visor is a snug fit when down, very little if any air coming in under the visor. My only complaint here is that the sun glare can make visuals opaque - this is the only reason I gave it a 4 and not a 5 on comfort. Bear in mind - this is sun in the face at 6:00pm, midday it's good. Chin Guard: TONS of air flow coming in through the chin guard - literally feel the air moving to the back and around my head. At a price of $70 - you seriously can't go wrong with this helm. Love the design too - went with the green one, wouldn't go back.

A nice & good construction helmet which it should give good protection. Visor and clear shield are useful. Chin guard is a nice piece and optional add on. It is light weight the internal pads are removable for cleaning is a plus. It is hard to say all. Overall, a good value & I like the helmet. Thanks and recommendation.

This helmet is super comfortable, nice and light. The inner visor is really nice, as is the quick release chin strap. I like that I can remove the face plate. XL fit me perfectly. I'm finally ready to go to space. It would have recieved 5 stars if the outer shield didn't fog up so much, nothing a little anti fog solution can't fix though.

This is a great looking helmet, perfect for summer, or warmer, weather. The face shield and front guard is two pieces that make this helmet excel, however there are some flaws. The front guard is janky at best to put on. Have to come in at an angle and even then it may not lock. Requires force to lock it down. The face shield covers the entirety of your face, not just your eyes. That means any upward wind will get into the helmet. The pros to this helmet are, it is very comfortable. The padding included fits snug and speakers installed are perfect against your ear. This helps with lots of wind noise. Another big pro. With the face guard and the sun visor down, it's dead quiet for the type of helmet this is. That even with tons of venting, and the for mentioned upward wind. You can't go wrong with this helmet. It looks good, has good functionality, and will serve its purpose flawlessly.

The helmet looks very cool. My issue is the chin piece isnt big enough/stick out far enough, if that makes sense. Essentially my chin rubs on the lower face piece and it makes the helmet unbearable. I was really hoping this would work, pretty bummed. The clear visor also fogged up terrible on me.

I recently purchased a Triangle brand motorcycle helmet, hoping for a decent blend of protection and comfort. Unfortunately, my experience has been nothing short of frustrating, and I feel compelled to share a negative review so others can be forewarned. From the moment I started riding with it, the air circulation was noticeably poor. Even on cooler days, I found myself overheating, and the lack of proper venting meant my head felt stifled and clammy. This isn't just uncomfortable; it's a safety concern, as it can lead to distraction. The lenses are another major letdown. They feel incredibly cheap and, worse yet, are constantly unclear. Whether it's fogging up or just a general lack of optical clarity, I'm constantly struggling to get a clear view of the road, which is absolutely critical for safe riding. It feels like an afterthought rather than an integral safety feature. The sizing is perhaps the most egregious flaw. I tried both a Small and a Medium. The Small was uncomfortably tight, digging into my head, while the Medium felt ridiculously loose, moving around far too much. It genuinely seems like they're using one shell size for all head sizes, simply padding it differently. This "one-size-fits-none" approach makes it impossible to achieve a secure, comfortable, and safe fit. To add insult to injury, the support for this product is practically non-existent. After only a few months since the helmet's release, there are no replacement parts available anywhere. If a visor scratches or a mechanism breaks, you're out of luck and essentially left with a very expensive paperweight. This lack of after-sales support is unacceptable for a safety-critical item. In summary, the Triangle brand motorcycle helmet fails on multiple critical fronts: poor airflow, substandard and unclear lenses, terrible sizing, and a complete lack of replacement parts. I strongly advise potential buyers to look elsewhere for a helmet that prioritizes rider comfort and safety.
