Wrangler launches first ever moisturizing jeans aka Spa Denim Jeans Image credit: Wrangler

They're smooth, they're silky and they promise to leave your legs feeling soft for days after you've worn them.

We're talking about Wrangler's newest line of jeans. It's called Spa Denim - jeans infused with high-performance skincare ingredients to keep your legs from cracking from the sometimes dehydrating effect of wearing denim.

Denim lovers can get their favorite skinny pair from a choice of three lines including Aloe Vera, Olive Extract and Smooth Legs. The price: a cool $140.

Model Lizzie Jagger is featured on the U.K. Vogue website wearing a traditional skinny pair.

"They definitely feel cooler than regular jeans," said Lizzie Jagger in an online promotional film. "After a day wearing them, my legs feel great - they come out feeling more silky than usual."

The effects of the moisturizers can last up to 15 days after your first wear, according to Vogue. After day 15, spa denim fashionistas will be able to purchase a spray formula that will keep legs feeling silky-smooth for up to 97 wearings.

But don't expect soft legs so soon. These smooth threads won't be available until Jan. 28 through ASOS, an online retailer based in the U.K.
