1] This year, Nike is celebrating the 10th anniversary of Tech Fleece with a series of special releases. We take a look back at the history of the innovative fabric.

2]Introduced in 2013, the first Tech Fleece pieces dropped as part of the Tech Pack under the Nike Sportswear label.

3] The lifestyle collection reimagined classic Nike apparel silhouette designed to meet the specifications of the world’s top athletes.

4] The campaign included stars such as Neymar Jr., Kevin-Prince Boateng, Rafael Nadal and Serena Williams.

5] Unlike traditional polar fleece, which was developed by Malden Mills and Patagonia in 1979 to mimic the qualities of wool with polyester, Tech Fleece is made from two layers of cotton jersey fused to a synthetic spacer.

6] The construction traps body warmth between the layers without adding weight to the fabric, while the smooth surface added lifestyle appeal.

7] The Tech Pack saw the Windrunner hooded jacket, AW77 hooded sweatshirt and N98 tracksuit updated with Tech Fleece material.

8] Beyond the material upgrade, the silhouettes were streamlined with fewer seams for added comfort.
