Review on Osprey Packs Handheld Running Flask by David Boone

I'm running. To mark. And I love running with gadgets, belts, etc. I also run in a fairly humid environment, so hydration proved to be an issue: my hip flasks caused chafing and my running vest was only good for very long runs. Portable Osprey Duro. This was the perfect bottle for me, keeping me hydrated in the heat for short, medium and long periods. Some reviewers have complained about the leak, but that wasn't an issue for me. If I could give six stars I would. worth your money!
