Ultimate Direction SJ 2.0 Ultra Vest, Gunmetal, Small;

The SJ Ultra Vest is the result of collaboration with Scott Jurek, the world's most dominant ultra runner. Weighing 11 ounces (16.5 ounces with bottles) and offering 7 L of storage space, the SJ Ultra Vest 2.0 has the best volume-to-weight ratio of any hydration pack on the market. Updated for 2014 to include Stretch Mesh, which is stronger and more durable and Sil-Nylon, for significantly improved seam strength, the SJ Ultra Vest 2.0 still retains many of its best features. The water bottle holders double as smart phone compatible pouches that cinch to keep phone or camera stowed away. Four gel or bar pouches, along with two electrolyte or valuables pockets keeps everything you need close at hand. An added zipper at the side of the pack gives you quicker access to the main compartment. Side adjustment straps, hidden in side pockets and two sternum straps offer a much better fit while securing the pack to your body preventing bouncing. Also includes two trekking pole loops and one ice axe loop for when you need your hands free.
