She added skinny pants to the look and walked through the concrete jungle in black loafers.

The former Victoria’s Secret angel protected her eyes with a pair of dark sunglasses.

She let her long brown hair fall in a single wave down the middle of her back.

Kloss’ husband, 37, wore a black T-shirt with a wilderness design that sat prominently at the center of her chest.

In the pictures, Gerber shows off her statuesque 5ft 9.5in figure in a black bikini top, which she paired with black patterned leggings and leather boots covered in desert dust.

As is usual for a proper “Brand” experience, she also had black goggles on her head in case the wind kicked up a storm typical of the region.

Kloss opted for a pair of white glasses for her ensemble, which included a pink mini dress and combat style boots.
