Striking pairings of black and white were all over fall 2011 runways, from Isabel Marant to Marc Jacobs. So leave it to hyper-fashionable British brand Sweaty Betty to stay on trend.

The Adrenaline pants are patterned black-and-white capris that are perfect for cold weather running. Reflective seams keep you visible in the darkness and the fabric offers some compression.

They’re for that woman on your shopping list who likes to bring style and wit to running the Reservoir or her nearly year-round laps of Prospect Park.

Just don’t let her wear these slightly mind-altering pants to yoga class. No one will be able to stay steady in tree pose with these in their view.
