UP was designed to fit seamlessly in people's lives. Real life. It's a thoughtful combination of engineering and design, custom-made for how we live. UP is both flexible and strong. Sometimes UP needs to slide smoothly under sleeves or bend to accommodate an active lifestyle. Other times it has to be strong enough to stand up to a snowball fight without a problem (or more likely, a few thousand showers). Day and night, UP is right there with you.
