At the core of every Diamondback system is the Diamondback Belt. The Diamondback Belt provides more comfort, support and options for customization than any other product on the market. Based on a lightweight, durable design, our belt distributes weight away from your hips for years of pain-free wear. The Diamondback 4in Belt offers the same comfort and customization options as the 6in Belt without the size. The 4in Diamondback Belt can be found on our Artisan, Chopo and Maestro Complete Systems. When to Choose the 4in Belt: Choose the 4in if you're looking for medium support and a smaller belt profile.
