The Ultimate Direction Access 20 Hydration Waist Pack keeps you comfortable and hydrated on long trail runs in the mountains or quick jaunts around town. Its Cool Wick Air mesh provides ample amounts of breathability to keep you cool and comfortable, and a bit of ripstop keeps everything together for a long time without adding weight. The straps offer a secure fit, and elasticated holders store the loose ends so you don't run with them flapping around. The Access 20 Plus features a semi flexible, angled bottle sleeve that allows you to take the included 20 ounce bottle in and out with ease while you're running, and the sleeve has a TPU backing to prevent the bottle from slipping out. The main compartment can store your smartphone as well as a few extra snacks or a packable wind jacket, and the internal divider will prevent the snacks from melting onto your phone. Ultimate Direction made the bottle out of BPA free polyethylene, and equipped it with a leakproof Kicker cap for your convenience. It features an extra wide mouth for easy filling and cleaning, and the mouth accommodates most water purifiers.
