Ultimate Direction designed its Access 10 Plus Hydration Waist Pack for long runs around town or quick sprints in the park. Its Cool Wick Air mesh and Power Stretch mesh provide ample amounts of breathability and mobility to keep you cool and comfortable, and a bit of ripstop keeps everything together for a long time in a lightweight fashion. The straps offer a secure fit, and elasticated holders store the loose ends so you don't run with them flapping around. The Access 10 Plus features a semi flexible, angled bottle sleeve that allows you to take the included 10 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. Ultimate Direction made the bottle out of BPA free polyethylene, and equipped it with a leakproof cap for your convenience. You can remove the accessory pocket and gel flask holder for the speedy runs, the main compartment can store your smartphone as well as a few extra snacks, and the internal divider will prevent the snacks from melting onto your phone.
