The latest in Nike's continued domination of the world of athletic apparel, the people over at Beaverton's Innovation Kitchen have set their sights on the now ubiquitous athletic jersey fabric. Constructed from a mixture of cotton and polyester, this thermal blend merges jersey with a synthetic spacer designed to retain body heat without adding weight. Taking a new approach to storage, the Nike Tech Fleece Short features an extended zip closed pocket and contrast logo and drawstrings.
