Nike ACG 1.3 Pro Series Daypack:
The product of years of adventure and endurance racing, the Nike ACG 1.3 Pro Series Backpack is an ideal race companion for ultra-distance and all-day events. You'll find that the dual-zipper, panel-loading gives you immediate access to your pack contents so you can grab your rain shell or other equipment quickly and efficiently without tunneling through contents like some top-loading packs. Zippered pockets in the shoulder straps give you just enough space for a couple of energy bars or gels. The 855-cubic-inch capacity gives you plenty of room for insulating layers and other critical items, so you'll never arrive at the start line feeling under-equipped.
