Definitely see an improvement in face skin. I use only Exuviance products and highly recommend them.

Before purchasing this backpack I owned a Camelbak which was good but more than double the price for a smaller bag with less features. I am so happy with this new hydration backpack! It has lanyards attached to the zippers for easier access, a better mouthpiece to allow more water flow, and tons of padding on the straps for when I run. The design is flashy and already I have gotten several compliments. Overall I love it!
