Keeping hydrated in the summer is crucial, but it's often hard to get in the recommended eight glasses of water a day. Skinny Water can help.

Skinny Water beverages, which are enhanced waters, do more than just refresh. Each beverage starts with super-purified water and adds a combination of electrolytes and an extract of green tea to promote hydration and nutrient-absorption.

Skinny Water contains no calories, sugar, sodium, preservatives or artificial colors. It is sold in 16-oz. bottles and is available at Target stores nationwide, supermarkets such as Albertsons, and drugstores such as Walgreens.

To help you stay hydrated this summer, AOL Health is joining forces with Skinny Water. Four AOL Health Facebook fans will receive a year's supply (360 bottles) of Skinny Water and a Skinny Water T-shirt.

Winners can choose from six Skinny Water flavors including Crave Control, a raspberry-pomegranate flavor; Shape, a goji fruit flavor; Wake up, an orange, cranberry and tangerine flavor; XXX Detox, a peach, mango and mandarin flavor; Hi-Energy, an acai, grape and blueberry flavor and Total-V, a lemonade-passion fruit flavor.
