Hydration Has Never Looked So Good

"“The Microlite 1000 is a unicorn. It’s remarkably light…and absolutely kicked ass in the thermoregulation test... It almost never pans out that the lightest, most affordable product also demonstrates the highest performance, but the Microlite 1000 really has it all. Its functionality blew my mind.”
