High-tech fabrics and crushable clothes don't have to mean ugly and utilitarian. Promise. Here's everything you need - accessories, too - to stay stylish on the fly, no matter where you go.
"Packable" clothes. Hmm. The phrase may call up visions of springy, spongy wads of whatnot more suitable for a science lab than a suitcase. Fear not. Travel and fashion are no longer mutually exclusive. In fact, they're on good terms. Don't look now, but stretchy, lightweight microfibers and quick-dry synthetics have gone positively fashionable to create sleek, smart clothing, gear, and accessories. So dressing well while on the road - whether we're talking sandals or sportswear, ski parkas or suits - suddenly looks a darned sight less daunting. Best of all? Form really does follow function this time. High performance, meet high style.

Got business? Think sleek, with suits of lightweight wool or wool-and-feather-light-synthetic blends. They fold well in your suitcase - and speak well in the workplace.
