The best 360-degree reflective running vest/chest pack: The Runtasty Hydrochest! Water-Resistant Cell Phone Pocket + Touchscreen Window + Sports Water Bottle! If you often find yourself outdoors after dark, you know how important it is to BE SEEN by vehicles, cyclists, runners, and anyone else. Accidents occur primarily because of poor visibility. But the Runtasty Hydrochest solves that problem for you. It gives you 360-degree visibility with a super-bright reflective material all around you. Its adjustable harness keeps everything right where you need it. It has a WATER-RESISTANT tilt-up cell phone pocket with a touchscreen-ready window – so you can access your phone and all its functions at a glance. (Has enough room for cell phones with cases ON and allows you to use the phone holder to shoot movies hands-free) This will free you up while you run, jog, hike, or bike. Behind your cell phone is where you'll keep your keys, cash, cards, and ID safe and moisture-free. That's not all. The Hydrochest comes with a BPA-free 12-oz (300 ml) sports water bottle – which conveniently attaches to the harness. (You can easily remove it for short sprints or jumping so it doesn't get in the way.) There's also a place for a small clip-on flashlight for when you're going to be in the dark. Nothing beats a flashlight! Unisex design, fits shirt sizes Small to Xtra-Large (US). Don't get caught in the dark without a 360-degree reflective Hydrochest!
