Review on Nathan Women's Hydration Pack/Running Vest - VaporHowe 2.0-12L Capacity with 🏃 1.6 L Water Bladder - Ideal for Running, Marathon, Hiking, Cycling, and More by Jeremy Jackz

first edition. I liked this vest and it looked a bit ugly so I decided to upgrade to the VaporHowe 2 12L. I've been wearing this vest for almost a week now. They chose the overall fit of this vest and it sits even more comfortably on my back than the first. I also have to say that I like the color, I think it will show less dirt than light blue. I would recommend washing the vest before using it with a light colored shirt, the purple bleeds a bit. I just rinsed it with vinegar so I didn't try again to see if that fixed the problem. The tank is slightly smaller (1.6L vs. 1.8L) than the original and seems to fit the vest a bit better, which may also help with the fit on the vest. The new bladder is insulated and I'm not sure if that helps or just makes my back hotter due to the heat and humidity of the SC. Waterproof bag - no! This is my only complaint. He only holds water. It is only waterproof on one side, the outside. So when you sweat, you sweat into the bag from the inside and it just keeps it there because it can't evaporate through the front.
