Review on 🏃 Osprey Duro 6 Running Hydration Vest: Optimize Your Performance with Superior Comfort and Hydration by Gabe Ries

I just ran an Infinitus Ultramarathon and really made it through this backpack. Fits great and doesn't irritate even after 50k! The pockets are simply arranged and offer great storage options. Bladder and quick coupler fill remarkably well at the auxiliary points. The front closure works great for me and I love the mouthpiece magnet. Such a big piece of kit around.
