Bring your next ultra to the next level with a lightweight design specific for ultra running, featuring waterproof pockets and efficient details dedicated to long miles. The Ultra Vesta uses the latest in fully customizable vest-fit technology with the ultra-durable Comfort Cinch™ 3.0 and protective mesh panels that prevent chafing over many miles. A narrower cut in the shoulder straps and back offers a more tailored fit for smaller frames than our vest version.
