VIDEO : Kate Middleton and Prince William Take a Hike in Bhutan

Kate Middleton has mastered the art of the quick outfit change and now she's onto hiking without breaking a sweat. On her second day in Bhutan, the Duchess of Cambridge proved she's in quite the impressive physical shape when she took to the mountains for a hike up to the Tiger's Nest monastery. With William by her side, the pair arrived several hours later. The 34-year-old mother of two epitomized CoverGirl's "easy, breezy, beautiful" tagline with her brunette wavy tresses framing her face, her skin glowing and her outfit comfortable and cool. William gushed to a group of reporters standing by. Kate chimed in saying, "We're really lucky and fortunate to see such beautiful scenery."
