What's our secret?
Daytona Helmets has engineered the lowest profile D.O.T. approved helmet on the market—period. Designed to be as minimalistic as possible while still meeting all D.O.T. safety standards, it’s up to 60% more low profile and significantly lighter than bulky competitor models. The result is a sleek, comfortable, and stylish helmet that delivers top-tier protection without the mushroom look. Safety never looked this good.
As the direct manufacturer, Daytona Helmets cuts out the middlemen and passes the savings straight to you. While major brands mark up their helmets 8–10x, we deliver top-tier quality without the inflated price tag. You get the same—if not better—protection, comfort, and style, all at a price that’s actually fair. Premium shouldn’t mean overpriced. With Daytona Helmets, it never does. Our product is affordable, not cheap.
At Daytona Helmets, our helmets are designed by riders, for riders—built with the same protection, comfort, and safety we expect for ourselves. Every model undergoes years of meticulous engineering and real-world testing to ensure it meets the highest standards before reaching the global market. We don’t rush perfection—we ride it, test it, and refine it until it’s perfect.

Overall rating: 4.9 / 5 from 25 reviews.
I love these helmets the way they fit an it's a perfect canvas for me to custom paint them.
Simple, classy, and gives me confidence every time I wear it. Thank you, Daytona, for making such a great helmet!
This is our third Daytona Helmet. We have a 1/2 helmet and two 3/4 helmets from Daytona Helmets. We love them all. Thanks for great products.
I hear my music better. Looks awesome. My bike sounds louder. I hope I never need it
I followed the size instructions and the 2X fit perfect Great quality face shield too
The first open face helmet I bought was from a well known company. I didn’t like the fit. It was too tall on the top and looked bad. I did more research on low profile 3/4 open face helmets. There a lot of companies selling the same one. Bad reviews very common. Daytona had a good rep. Fit was great, and comfort good. Hope it gets better when it’s broke in, but overall very happy.
I'm a newbie biker, but I love classic bikers. I already have a 1/2 helmet, but my ears get clogged after 50 miles. I decided to buy a 3/4 Daytona cruiser. I really liked it. My head is 57 cm, so I took the size exactly according to the chart, and it fits very well. The noise from speed has noticeably decreased, but I still want to try it with earplugs. The helmet is lightweight and very well made.
Getting geared up for some vintage trials competitions in 2026. This helmet is perfect!
Nice helmet
Love this thing! Fits great and low profile. Plus the chin strap is very easy to use. The helmet is a great value.
Nice lightweight helmet. The buckle is pretty cool, no D-rings to mess with. Fit is perfect, exactly as measured.
It’s a great fit, looks great but wished there was an option for double D-Rings strap. Nonetheless, I love it!
The Daytona Helmet is a perfect fit, the 2XL fits my size 23 1/2 inch hat size according to the size chart and recommendation. The lining is excellent and should conform to my head. The low profile works well with the windshield on my bike as to turbulence. I would highly recommend.
ytona Helmets delivers next-level customer service—professional, responsive, and truly rider-focused. I picked up their Cruiser 3/4 helmet and it exceeded all expectations. My head measures 58.5 cm, and I went with a size Small for that perfect snug fit. Couldn’t be happier. Highly recommend both the product and the people behind it!
Excellent helmet I have purchased 3 of them and the fitting is perfect I really like them I’ll definitely purchase more of them as needed. I did have a problem snapping the visor on this one I just hope it doesn’t fall off. Middle snap did not want to stay on
Fast shipping and good product.
Lightweight and fits great
Bought my Cruiser helmet at Biketoberfest ‘24. Kyle’s customer service was excellent. He helped me get the right size/fitment, next day shipping to my home was included, along with a military discount. Helmet fits great and is perfect for touring the back roads and urban areas of north Florida. The Cruiser will be a perfect helmet for The Distinguished Gentleman’s Ride 2025.
I bought my Cruiser helmet at Biketoberfest, my first Daytona Helmet. It’s perfect!! Great for casual rides around town and touring back roads. The smaller, low profile shell fits and looks great. It’s a 5-star helmet
Exactly what I was expecting.
fits great, looks great! I got the white one and will soon be getting a back up in black.
These helmets fit steady, and comfortable. Light weight and great visibility for safe riding
The Daytona Cruiser 3/4 helmet fits well, tightly enough to feel secure, but not uncomfortable. It doesn't slip back on my head at speed like most 1/2 helmets do. The quick fasten/release tab is a nice touch, I can do it even with gloves on. The goggles retainer at the back keeps my goggles in place whether down over my eyes or pushed up on the brim. And it looks really cool, with a vintage vibe. Its slim profile keeps me from looking like I have a giant mushroom perched atop my head!
Exactly as described. I like the modern buckle. Very comfortable and convenient to use. The helmet is definately smaller in over all size than the 3/4 helmet it replaces and quite a bit lighter. Have only worn it riding three times so still needs to be broken in. So far very pleased with it.
Great helmet Cruiser 3/4 helmet Fits perfectly. Snug but not too tight. The neck strap feature is great! The basic white is perfect for custom paint.
