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

When I received this backpack I didn't think I would like it. Looked really big. It's all well balanced, and even with 2 liters in the bladder (it holds 2.5) it still felt so good. You couldn't even feel the weight of the water. There were pockets everywhere that you could reach without taking off! They have a little at the waist and more along each chest pocket. My cell phone is even suitable for the breast pocket without a case (Samsung Note 9). No more mixing keys with gels and everything else you want to carry since your phone is in another bag! There are 3 large areas in the main body: one for the bladder, another for a coat or pants, and a third for a helmet. There were also 2 small pockets on the main body for keys, wallet and more. One thing about this backpack is that it's really made for long hikes, marathons, ultra races, and biking. It's designed to carry everything you need with you and be as comfortable as possible. It's quite large and comfortable, but still weighs you down a bit. Even women with medium to large breasts may find it difficult to feel comfortable in this backpack. Something could come up.
