Osprey Sylva 5 Women's Bike Hydration Backpack with Hydraulics Reservoir

This is my first hydration backpack and I really like it for the most part. First, the good parts, this backpack fits me really well. I'm a slender woman and this backpack is the perfect size for my back. The chest and waist straps make it so that the weight isn't on my shoulders and neck. The mesh frame on the back adds a little bit of weight to the backpack and I was concerned at first, but with the chest and waist straps, I don't feel the extra weight on my shoulders. I love the mesh back. It is very breathable and my clothing doesn't get sweat on it in the same way it does with a regular backpack. This back has enough room to carry a decent amount of things. I was able to fit a battery pack, my wallet, several energy bars, and a pair of glasses in the pouch and still had some room left over. The water bladder system works well. The top folds over and hangs onto a clip. I haven't had problems with leaks and the system works in such a way that I think a leak would be unlikely.

Love this water pack. Easy to fill and use. Love the mesh that sits away from your back. Has great storage options with a few pockets and options to attach. Great for long hikes and bicycle rides.
