That looks like the one I have. Mine is a couple years old and I think it might be a little smaller. I never use mine, but not because the design is bad. The women's specific fit is great for my petite build and I recall it was very comfortable for my first organized ride (50 miles). Personally, I like to use water bottles and not deal with anything on my back.
When I did use it I always put water and ice in mine and energy drink in the bottles. This is another personal preference, I can tolerate warm energy drinks over warm water.
