During the winter I really try to stay hydrated, Core is great tasting and has a higher PH so your electrolytes are balanced and your skin is moist!! I got thru a case in a blink of the eye, so Amazon makes it easy to reorder frequently, no lugging cases of H2O out of the market and up your stairs!!!!
I have been drinking this brand of water for a long time; in fact, I have it on a subscription. It has my recommendation, but beware of the pricing. Some vendors charge outrages fees for this product. Look for the best price.
