Reviews

  • Black and white photo of a man standing on a boat fishing in a lake surrounded by tall trees.

    Nothing beats the feeling if training with these shorts. Flexibility, freedom, awesome quality!

  • A black and white photo of a classical cityscape featuring a tall building with a square top, a clock tower, and a domed church in the foreground.

    So happy with how these shorts fit, and look! Everyone around me is constantly asking where I got them and I have never been more happy to share. Will be buying more soon!

  • A text image with the phrase 'Ready to go' in black on a white background.

    They look small when you open the package but they fit like a glove! Compressed in all the right places and feel nice. Can’t wait to get more colors.

  • A close-up of a black and white dog with its tongue out.

    These are amazing shorts from the quality to the fit (true to size). I'm 5'10" and 170 lbs and purchased a L (with a muscular build). I love the baby blue and will be purchasing more in the future!

    Perfect fit, the booty is bootying! High quality fabric. I recommend!

  • A close-up of a plant with green leaves in a pot, taken indoors with a blurred background.

    Beautiful fit! This brand is dedicated to making sure people of all sizes can enjoy their skin shorts. I'm already thinking about my next order. Shipping to Canada went smoothly.

Not a playlist. A pulse.

Bootlegs that sweat, edits that bruise — built for training runs, club floors, and everything in between. Ultra Radio is our channel for motion: SoundCloud sets cut to move the body, made to be felt, not just heard.

  • Bodies are complex. So are we.
    Our design fuses sport logic with graphic language — silhouettes cut from muscle, sweat, and speed. Every piece is built to perform in motion: studio to street, club to gym, pool to sun.

  • ULTRA rejects toxic masculinity and narrow ideals. We design for athletes, outsiders, and everyone in between — trans, queer, strong, soft, all shapes and sizes. Movement belongs to all of us.

  • Italian fabrics, Tel Aviv & New York design, Xiamen precision. Every product is shaped by a multicultural team working as one. Built to last. Built for performance. Built for you.

  • ULTRA lives where bodies train and celebrate side by side — running clubs, Pilates classes, and open workouts by day, loft parties and nightlong sessions by night. Different stages, same energy: sweat, movement, and community fused into one performance.

Born from sport. Made for life.

Our new swim collection is here — bold, body-focused, and built for performance. Featuring striking cuts, premium fabrics, and our signature FLASHMODE™ reflective detailing, each piece is designed to move with you from beach to club. This is swimwear that performs as hard as you do.
