Prabal Gurung Sport

Bold color-blocking, eye-catching design, and superunique lines combine in the ultimate high-end fashion-meets-function collection from Prabal Gurung at Bandier.

adidas by Stella McCartney

You can always expect to see gorgeous styles year over year from adidas by Stella McCartney.  This season, we're loving soft purples, mixed prints, and subtle metallics.

New Balance x J.Crew

Two of our favorite brands joined forces this year to create the ultimate New York prep look for athletic activities.  Clean lines, staple neutrals (with pops of bold solid colors), and a few polka dots and stripes here and there make for a fun yet classic collection from J.Crew and New Balance.

Tory Sport

If you love the sophisticated (with a touch of retro) style from Tory Burch, you'll love the activewear from Tory Sport.  With a distinctly 1970s aesthetic, your look will definitely stand out from the crowd in the studio.

Kate Spade x Beyond Yoga

The preppy, feminine chic of Kate Spade meets ultrasoft, flattering styles from Beyond Yoga, making for the ideal collection for a girlie yogi or any active girl who loves pink and bows.

NikeLab Gyakousu

This year's lineup from NikeLab Gyakousu uses subtle neutrals and muted tones with bold, distinctly unique designs for running gear and beyond.  Longline vests, high-top sneakers, and t-shirt dresses are just some of the gems you'll find from their line this year.

Reebok x Gigi Hadid

Gigi's activewear game has always been fire, and now she's teamed up with Reebok to create an aesthetically on-point collection of active styles that are perfect for her favorite workouts, including boxing.

Julianne Hough x MPG

The Julianne Hough collection with MPG Sport brings the dancer's iconic fashion sense to life with an athletic look that can easily translate to street style.  The on-trend silhouettes and playful use of color make each piece impossibly cool.

Derek Lam x Athleta

Gap brand's Athleta is known for supersoft materials and functional pieces for the gym, so the Derek Lam x Athleta collection is just as fashionable as it is functional.  The line features pieces that are ideal for the gym, and even some transitional pieces to change into after you shower so you can head straight to dinner and drinks on the town.

Fitbit x Vera Wang and Public School

Fitbit's collaborations with Vera Wang and Public School have yielded some edgy and stylish bands and covers for your sporty tracker, making it easier than ever to go from gym to street.
