For Nike ACG, and life in the outdoors, it's about maximum mobility using lightweight fabrics that offer protection from whatever nasty environment you put yourself in. That's why we use Clima-FIT Ultra Lite.

Clima-FIT Ultra Lite is a moisture- and wind-resistant fabric by virtue of its construction. It's secrets are the weave and the fiber: Its densely-woven 100-percent polyester microfiber filaments (.69 DPF, denier-per-filament) repels water without the need for coating materials (surpassing the Hydrostatic Suter Test for water-resistance). The result is ultra-light weight fabric-80 grams per meter squared, the lightest weight in the outdoor market-that's windand water-resistant, surpassing Clima-FIT for extreme weather protection and comfort.

"For it to maintain the level of water resistance and still be lightweight requires really new technology, very high microfiber," says Tina Baer, Nike ACG Materials Manager. "It's woven very tight, without a coating. And it's ripstop. Normally you can't do this with ripstop. Water gets through the crosses. This material will keep you dry and warm, the wind won't get you, and it makes a very packable jacket."

Look for it in Oregon Series apparel like the Oregon Shell Jacket, and Oregon Shell Pant.
