The outer shell does not seem solid as other helmets i used to have but for pleasure riding, this one is great. ### ⭐⭐⭐⭐⭐ Anxious buyer who is VERY HAPPY!! *by T***D on Reviewed in the United States on August 28, 2019* Reviewer: Female Tall/Fit pillion rdr.Only put 200 summer miles on this helmet and I am pleasantly surprised. The visibility is great, it vents ok (tho could always be better in our 100°+ heat 😩, very comfortably padded, low noise, looks good. It's a great value! I now realize how much my old B€ll helmet sucked.Cons: The inner visor comes down really low and hits my nose.I measured as a medium and had to send it back for a large.I dislike the double ring chinstrap design.Will update. ### ⭐⭐⭐ 4/5 rate *by D***N on Reviewed in the United States on May 27, 2019* It's a pretty good helmate for a spare or for short commutes. I have just a few gripes with it. I use this as my daily helmate and it is comfy but I do have a few issues with it that I think could be improved.First- visor. The built in visor the mechanism the bring it down the sunshade inside the helmate is terrible. I hardly use it because it sucks that bad. Not very intuitive.Second- I wish the helmate had more adjustment point on the shield. You can only have it open half open or closed. It would be nice to have more adjustments so I could even have the shield cracked open and let air in but keeping it mostly closed. --- ## 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.us/products/63241748-gdm-duke-helmets-dk-350-full-face-motorcycle-helmet-matte](https://www.desertcart.us/products/63241748-gdm-duke-helmets-dk-350-full-face-motorcycle-helmet-matte) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
