In most other brands, that equates to a "large".These helmets are amazingly round. So much so, that the large puts a tremendous amount of pressure across my forehead, even with all the padding.Because I was determined to support this brand because of their quality, the low profile appearance, and the variety of colors that are offered, I ended up ordering an extra large helmet, and then a large size replacement liner. That combination works out perfectly for me with my fairly "normal shaped", 7 1/4” head.(The long oval, on the other hand, was excessively "oval", leaving far too much room across the forehead.) --- ## 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.com.ar/products/56635371-one-k-unisex-defender-protective-riding-helmet-brown-matte-large](https://www.desertcart.com.ar/products/56635371-one-k-unisex-defender-protective-riding-helmet-brown-matte-large) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
