Review: For the price, one great dual sport riding helmet - Great helmet for the price. O'Neal dud a great job with the engineering aspects. Very comfortable, well padded, full face coverage keeps the wind off your face, much quieter on windy rides, sun protection visor for sunny days. Face protector visor easily retractable. Liked mine so I ordered one for my wife as well Review: Yes, you need a sun visor - In my opinion, this helmet hit a home run. I've only had it for a few weeks but the quality seems to far surpass the value. I like the silver/gray color scheme a lot and I love the sun visor. I do wish it had more vents since I live in the heat but it's fine. There is some wind noise but I think that's the nature of the beast. Sometimes there are sacrifices for such a low price but I just don't see it in this particular item. Update#1 As an addition, I am a tweener at 23" - between MD and LG - so I went with the LG. I got it, I wore it around the house and it felt snug; however, after many rides later, it does seem to have broken in to an ever so slightly, loose fit. It's possible a MD would have been a better choice. Update#2 I recently noticed that the screws to the visor were very loose. Get some blue loctite on those before you lose them. ## Features - Shell is constructed with ABS - Weight: 1590G ( 50G) - Moisture wicking, removable/washable air channeled comfort liner - Integrated face shield - Padded chin strap with double-d safety lock.

Enough air that my glasses won’t fog up ? And will the shield fog up itself?** A: I don’t wear glasses but there seems to be enough room. I have not had any issues with the shield fogging up. There seems to be enough air flow through the front vents **Q: How do i know if i order i will not get a left over year of manufacture? what year is printed in these helmets?** A: You get a helmet that looks exactly like the one you order. I don’t know what year it was made. But you don’t get a different helmet. Like a previous looking model. You get what’s pictured. It’s not like a car. **Q: does the visor protect you from UV?** A: The description says yes **Q: Is this helmet super loud on the highway?** A: Yes, it is significantly louder than all of my other helmets. I usually wear a good set of ear plugs with this one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ For the price, one great dual sport riding helmet *by J***N on November 26, 2025* Great helmet for the price.

Worth the money. Are well made - run tight, but that might be a far better design. You want 'hamster cheeks' in a good helmet. Their outer transparent visor seems thicker than many offerings. I'd love to see an O'Neal helmet with an in-built auto brake sensor light -- there are clip-on VERY HIGH-QUALITY brake light offerings that some manufacturer should license and build it into a helmet. Worth a big premium. ## Frequently Bought Together - O'Neal Sierra Helmet - Seibertron Unisex BMX MX ATV MTB Racing Mountain Bike Bicycle Cycling Off-Road/Dirt Bike Gloves Road Racing Motorcycle Motocross Sports Gloves Touch Recognition Full Finger Glove - O'NEAL Element Dirt Bike Boots --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/46248470-oneal-sierra-helmet-flat-black-lg](https://www.desertcart.pl/products/46248470-oneal-sierra-helmet-flat-black-lg) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-25*
