Starting at just 1.18 kg/2.6 lbs, the new X1 Carbon is the lightest 14-inch business Ultrabook™ on the planet. And at just 16.5 mm / 0.65 inch thin, it's extremely portable.
Lightest 14-incher Yet” — LAPTOP,January 3, 2016
©Constructed™ with satellite-grade carbon fiber, the new X1 Carbon is the toughest ThinkPad ever made. In fact, we perform nearly a dozen separate military-grade specification tests—all under extreme conditions with dust, vibration, heat, cold, altitude, humidity, solar radiation, and fungus. You can rely on ThinkPad despite what life throws your way.
And of course, the full-sized, backlit keyboard is spill-resistant, as you’d expect from a ThinkPad X1 Carbon.
The military specification tests are not intended to be a guarantee of performance under these environmental conditions.
