Durable and looks tough *by A***E on Reviewed in the United States on January 15, 2024* Husband loved this very comfortable for long periods of time. Came with several different shields Looks really good and does not scratch easily. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great looking helmet *by D***7 on Reviewed in the United States on February 24, 2021* As far as the overall looks and design of the helmet I for one would be hard pressed to find one anywhere at any price I liked better. For openers it’s not a gigantic mushroom on your head. It’s sleek, the visors are great and it fits snug. The reason for 4 stars however is it seems to me to be poorly ventilated but maybe it’s not much different than most. The only thing is I don’t see how it could be any less hot because the vents in front are minuscule when all is considered. Aside from that it’s made well and I’ve taken it apart and it goes back together fine. The only other criticism would be the chin strap which didn’t work for me. It worked but I didn’t like it so I modified it. Other than that it’s a great helmet.Edit* I changed to 5 Stars because the helmet has held up well after a year and after contacting the seller they took care of my broken visor attachments. Good customer service. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Get a medium size *by M***E on Reviewed in the United States on February 23, 2021* Good helmet for the most part, my bike has short swept pipes, the helmet drowns the noise a good bit and still am able to hear vehicles on my side, haven't installed the tinted visor yet.. the clear one is decent., Little fog on cold rides.. however.. not the most aerodynamic helmet.. @70-90 wind drafts will catch it.. just got home from an hr. Ride home from work tonight.. I feel I should have bought a medium instead of large when it came to this helmet.. top of the head fits well, kind of loose on the cheeks and chin being that I am an average guy of 6'2 170lbs.. go with a medium on this if youre not fat faced.. --- ## 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.pt/products/129680961-gdm-dual-sport-motorcycle-helmet](https://www.desertcart.pt/products/129680961-gdm-dual-sport-motorcycle-helmet) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
