Think about your favorite piece of clothing. The one you pack every time you travel. It's the shirt, pants, or skirt that's made well, lasts forever, and that you can dress up or down.

Clothing from Patagonia hits all those marks. They use advanced fabrics and flattering styles to make apparel that you can shove in the bottom of a backpack, throw on for yoga class, or wear to dinner. They use organic cotton, wrinkle-resistant nylon, and moisture-wicking jersey fabrics cut to maximize mobility, comfort and plain good looks.

Patagonia's 30% Summer Sale runs through 7/29, and it's one heck of an opportunity to build a whole wardrobe of favorite pieces.
