CIRQ™ In snow-capped mountain ranges, one of the most visually stunning sights you’ll find is a cirque. These concave valleys are formed by glacial erosion, creating an almost amphitheater-like natural bowl in the mountainside. We at CIRQ aim to create outdoor garments that will help get you out in the wild so you can see these marvels for yourself. Whether you’re on a winter ski tour, a mountain hiking trip or a trail running adventure, CIRQ has all of the tech you need to get the job done. Refined color palettes and subtle detailing create a look that’s as much at home in the city as it is on the snowy slopes.
