We strap on the Pinnacle 4L Hydration Vest to ensure our muscles keep getting the oxygen and fuel they need to make serious elevation gains during our Pulpit Rock training run. We huff, "I think I can, I think I can," as we chug toward the summit with our excess heat rising out of the tapered, chimney-wicking back panel, keeping us cool, while the stretchy fabric and adjustable sternum straps give us a no-bounce fit to make our grueling miles as comfortable as possible.
