You’re no NASCAR fan; you’ve got enough racing around of your own to deal with.

World-record holder for the fastest trip through a grocery store? You. Winner of the death-defying, day-to-night outfit switcheroo? You again.

Clearly, you need a bag that keeps up with your speedy lifestyle. Like Bianca, Lauren Merkin’s latest. It has the feminine, tailored look of the New York designer’s earlier bags but ventures a little farther downtown with playful stripes and a roomy, slouchy shape. Two outside pockets keep essentials handy for sudden cell phone/house keys/credit card searches. Metallic accents add flair without making you look like a Solid Gold refugee.

And if you ever decide to downshift, Bianca looks just as fierce on a casual jaunt-about-town as she does at warp speed.

See you at the finish line.

Available at Girl Stuff, 2255 Polk Street, between Green and Vallejo Streets (415-409-2426). To see styles, go to laurenmerkin.com.
