Excellent jacket, great fit. Just wish it came with level 2 armor!
It’s a worthwhile investment. Little longer than my other jackets which is nice. If only it had Level 2 armor….on back order for another $125 or so I guess

Amazing jacket! Amazing customer service!
This jacket has far superior air flow and is much more comfortable than any previous jacket I’ve owned. Well worth the money!
Also, the customer service received was phenomenal! I had a question, on a Sunday night, texted the number on the website and had a response within minutes. Who else does that!? An actual response, from a human, on a Sunday night! I will never buy gear from anywhere else. Thoroughly impressed with both the jacket and the customer service!

Solid helmet...
The HJC i31 helmet was a good choice for me as I updated from another HJC open face helmet that was over 5 years old. Like the last helmet, this one is comfortable and has features and styling that I like a lot.

Outstanding.
Outstanding helmet! The Arai Contour-X is extremely comfortable, well-built, and feels premium in every detail. The fit is excellent, ventilation works great, and it feels very stable while riding. The Samurai 3 graphic looks even better in person. You can really see the quality and craftsmanship Arai puts into its helmets. Very happy with my purchase and definitely worth it. Highly recommended!

best helmet i own. definitely worth the premium cost.
so it turns out the expensive helmets actually are better. my previous helmet is a Bell Bullitt Carbon and it clearly prioritized retro styling over comfort. it is unusable with speakers and the ventilation is almost nonexistent. i didn't think the ventilation was that bad until i tried the Corsair X. wow, you can actually feel the breeze inside the helmet, drying the sweat off my lips and forehead. and with little to no wind noise! incredible helmet. super comfortable. if you live in a hot climate (i'm in Houston), the extra cooling alone is worth the price premium over whatever other helmet you're considering.
