## Description

With the SHEATH 3.0 Zen, we decided to take what makes SHEATH Underwear so great and give it an extra dimension of luxury. Created with an exquisite blend of 95% Modal and 5% Elastane, this model seamlessly combines functionality and elegance. The silky, yet elastic and breathable feel of the 3.0 combined with the wide aztec geometric waistband (courtesy of our friends at TIMEWHEEL) really places this model into a category of its own in terms of style and comfort.
