A new take on a classic style. The Ultra Handheld features a 17-oz Quick Stow flask that molds to the shape of your hand. The 3D ventilated mesh material is comfortable and breathable over the long haul, and the integrated phone pocket has a zippered closure for added security. The elastic X-Grip strap system ensures a stable carry, and there's even reflectivity and an extra stretch pocket for additional gels or trash.
