Review on Phoenix Red Osprey Duro 15 Men's Running Hydration Vest - Medium/Large Size by Chris Bertoli

I've been using my Osprey 15L backpack for over 2 months and absolutely love it. I used it on the longest end-to-end Grand Canyon hike of my life last month and it worked like magic. Extremely good and thoughtful functional design, worked well for my 50 mile trip. As does the fact that it has a 2.5 liter water tank compared to others that only had 2 liters which makes a big difference during strenuous outdoor activities. Must have for long hikes Highly recommended!
