Engineered to the exact specifications of championship athletes, the new Fall 2014 Nike Tech Pack collection, featuring an updated Tech Windrunner and all-new Tech Butterfly, has just arrived. And we love it.

Fleece is the fundamental material of sport. By re-examining the textile and fabrication, Nike has evolved the timeless basic into a modern staple. With Nike Tech Fleece as its champion, the Fall 2014 Nike Tech Pack Collection will offer increased functionality, instant-classic silhouettes and time-honored styles.

Since its debut in 2007, Nike Tech Pack has stood for forward-looking design with an emphasis on uncompromised function. Nike Tech Fleece, introduced in 2013 and created for the contemporary athlete, reimaged classic Nike silhouettes with an advanced fabric saturated in benefits such as superior breathability, insulation and articulation.

This season brings two key styles to Nike Tech Pack Collection, emphasizing movement and environmental protection.

For women, the Nike Tech Butterfly Jacket is a fresh silhouette that elegantly plays with proportion. An oversized hood and dolman sleeves that transition to a fitted, feminine cuff allow for a greater range of motion and flattering fit. An asymmetric front zip and contrast-color zipper pulls are fine details that complete the package. Accompanying the Nike Tech Butterfly Jacket as part of the new collection are the Nike Tech FZ Hoodie, Nike Tech Funnel and Nike Tech Pants.

The complete Fall 2014 Nike Tech Pack Collection featuring Tech Fleece will be available online at nike.com/techpack and in select Nike Sportswear retailers worldwide.
