Bringing along a pack or vest on long runs is always a dilemma. On the one hand, they fit everything you need, but on the other hand they can often be bulky and uncomfortable. Well, with the comfort, light weight, and easy-packing storage of the Ultimate Direction Halo Vest the decision's a lot easier. Its breathable construction and easy adjustment deliver loads of comfort as you run, even on the most intense runs and hottest days. Two included 500ml water bottles sit in front pockets for quick-access hydration, while stretch mesh pockets at the front and back give you space for all the packable layers, energy gels, and media devices you need to bring along. There's even space in the main compartment for an extra hydration reservoir, complete with a hanging loop to keep it from slipping and sliding as you run. Front trekking pole holders keep your poles at the ready for steep and technical mountain terrain, and snap out of the way when they're not being used.
