Are these cardboard cup wraps the most efficient way to keep your drink hot while protecting your hands? No!

The colorful Kup Kollar cup cozy is insulated with Thinsulate insulation by 3M which is used in ski wear and winter clothing. This light weight insulation is almost one-and-one-half times the warmth of down and twice the warmth of other high-loft insulation materials.

What would you rather wear to stay warm – a cardboard winter jacket or a Thinsulate insulated one?  Remember this the next time you want your coffee or tea to stay drinkable for 30-40 minutes!
