Works Great for long distance running!
Wish I would have bought this years ago. After local watering fountains have been closed this year due to COVID, I decided to finally give one of these a try vs. hiding bottles ahead of time. I've tried hydration belts in the past but always was bothered by the constant up and down movement. This Camelbak is great! It holds plenty of water and doesn't move when running. Adjustable to fit snug but not too tight. Doesn't move when full or empty. Love it!
