Review on 🏃 CamelBak Arc 2 O/S 10 oz Hydration Belt Pack - Unisex Adult by Brian Cooper

Great product! There is no rebound when running, so it doesn't bother me on long runs. The bag is super snug with an iPhone 6 in it and swivels a bit on my hips when I'm pre-freezing water bottles, but I definitely prefer to run with a backpack or portable water bottle. I wish there was a bigger water bottle. 20 ounces of water is only enough for me in the summer, so I had to plan my routes around flowing fountains to compensate, but it's worth it since backpacks get in the way of my running.
