On Ultra Vest Pro Unisex

Engineered for the most demanding trail runs and tested and approved by elite athletes, the On Ultra Vest Pro is the next generation trail vest with a body-hugging fit, optimized storage, and clever details for maximum performance in alpine terrain. The vest comes with two 500ml BPA-free Hydrapak® flasks, so you’ll always have enough hydration at hand. The updated fit eliminates bounce, while a removable, seam-taped dry pack with a water-resistant zipper keeps your belongings safe and dry. Strategically placed front and back pockets give you quick access to essentials like nutrition or your phone. A safety whistle, extra loops, and modular attachment points – including for the Ultra Quiver – complete this vest for technical and long trails.
