As the next generation of the VaporKrar race line, the Nathan Pinnacle 4L Hydration Vest continues to offer a second-skin feel and top-of-the-line comfort for your long trail race or training run. With improvements to the overall design and shape, this vest is now 20% lighter and more breathable and features a slightly longer back to disperse pack weight. This pack's soft, shirt-like material adapts to your body to maintain all-day comfort, while adjustable sternum straps provide a personalized fit.

Dual holsters on the chest straps offer two 590ml Soft Flasks with extended straw tubes for hands-free access to hydration. Offering up to seven convenient front pockets and holsters, there is more than enough room for a day's supply of gels, capsules, accessories, and extra bottles.
