Warm Coat
I’m extremely happy with the 2026 Karbon Radon jacket. This is my second Karbon coat in this style, and the updates they’ve made genuinely improve an already strong design. The phone pocket placement is excellent — easy to access, secure, and perfectly positioned so it doesn’t interfere with movement or layering. It’s one of those small details you only really appreciate once you’ve used it regularly. The side zippers are also very well thought out. They’re set at exactly the right height to comfortably access pants pockets when needed, without having to awkwardly unzip the jacket or bunch the fabric. It’s a small but very practical design choice that makes daily use easier. Compared to my previous Karbon Radon, the refinements in fit, pocket layout, and overall usability are clear. Karbon didn’t try to reinvent the jacket — they focused on meaningful upgrades that improve the overall experience. Overall, this is a well-designed, practical, and high-quality jacket. While it’s clearly built for performance, I’m using the Radon primarily as a commuter coat for going to work, and it performs exceptionally well in that role. The comfort, clean look, and thoughtful functionality make it ideal for everyday wear in colder conditions. Based on owning two versions of this jacket, Karbon continues to earn my trust for outerwear that’s functional, refined, and designed with real-world use in mind.
