Since it's debut in 2007, the Nike Tech Pack has introduced forward looking designs with unparalleled function. Just last year, Nike continued their evolution by introducing Tech Fleece, bringing this timeless sporting fabric into the modern era making it more breathable, and insulated. With the Fall season just around the corner, Nike debuts the 2014 Tech Pack Collection which focuses on emphasizing movement and environmental protection in both men and women's styles.

For women, Nike rolls out the Tech Butterfly Jacket, featuring an oversized hood and dolman sleeves that flow into a fitted cuff to allow for a greater range of motion and more natural, flattering fit. Along with the Nike Tech Butterfly Jacket as part of the new collection are the Nike Tech FZ Hoodie, Nike Tech Funnel and Nike Tech Pants so athletes can be comfortable from head to toe before and after competition.

For men, the Nike Tech Windrunner IRD takes from the jacket designed for Nike runner's in 1978 and re-imagines to today's standards. The jacket features water-resistant iridescent woven overlay to increase protection from precipitation, and is finished off with an extended hood bill and reflective zipper for a unique look. The collection also includes the Nike Tech AW77 with iridescent overlays, the Nike Tech FZ Hoody, Nike Tech Crew and Nike Tech Pant.

The collection is featured by some of Nike's most iconic athletes including Karlie Kloss and tennis stars Serena Williams, Genie Bouchard and Rafael Nadal, who will all be outfitted with the Tech Pack collection when the US Open descends on New York later this month.

The men’s and women’s Fall 2014 Nike Tech Pack will be available online at the Nike Store beginning August 21, and will hit select retailers starting August 28.
