Overall great product. I was apprehensive about ordering online but the sizing was accurate and fits great.
Great packaging, Great fit and awesome look!! I also purchased some goggles to go with. You can’t go wrong with Biltwell inc!
For years if i had a helmet on it was a novelty for riding through helmet law states. This year when the bikes came out I dropped my novelty and watched it crack apart. I told my man i was getting a real helmet. He laughed and said “your head your choice”. He does own and occasionally wear a DOT. Helmet. I had decided i wanted more than a beanie and found the biltwell 3/4 gloss black. The sizing runs dead on. I got a s and it fits perfectly. No bad wind noise and it stays sput have worn it on several multi-state rides with no complaints. It is heavier than my novelty but There is an actual helmet on my head now and not a a worthless plastic cap. Glad I bought it. ride on
This helmet is gonna be the saving grace this summer. I love the brand and the full face ones but when it’s time to cruise in the warmer weather, this will be my go to!
This helmet is super comfortable. It feels sturdy and safe but is also lightweight. 10/10 recommend buying this helmet.
