Kendall Jenner is starting the new year off strong.

On January 3rd, the model, 27, was spotted slipping out of a hot pilates studio in West Hollywood outfitted in a black sports bra topped off by an oversized brown leather jacket paired with what appears to have become her favorite pair of leggings.

This is the fourth time we’ve seen The Kardashians star out and about the High-Waist Airbrush Leggings from celeb-loved activewear brand Alo Yoga. We’ve also spotted her wearing them with everything from Ugg boots and sweatshirts to sports bras and sweaters. Plenty of other stars like Alessandra Ambrosio, Camila Cabello, and Emily Ratajkowski have worn workout gear from the brand too, including bike shorts, sports bras, and flared leggings.

Black leggings are no doubt a workout staple, so what makes this particular pair Jenner keeps wearing so special? Alo’s signature Airbrush fabric is a nylon-spandex blend that “sculpts” the legs with just the right ratio of stretch to compression.

The high-rise silhouette creates a leg-lengthening silhouette, and reviewers say the waistband doesn’t dig in or roll down while getting active. The inseam of the standard length is 28 inches, but the style also comes in a petite-friendly version with a 24-inch inseam. Plus, they’re moisture wicking and odor-resistant.
