Description

Built to support serious athletes, the Ambar Wear Cross-Back Sports Bra combines reliable support with everyday comfort and visual appeal for demanding workouts. Its distinctive cross-back straps and compression knit construction provide dependable stability through gym sessions, CrossFit, yoga, Pilates, and rigorous training—all without underwires, clasps, or extra bulk.

Made from a responsive nylon-spandex blend, the material stretches in four directions while keeping compression steady during your session. Its knit structure breathes easily and pulls moisture away from skin, regulating temperature and keeping you fresh from start to finish. The fabric contains no harmful chemicals, making it ideal for reactive skin.

The cross-back arrangement spreads strap force evenly along your upper back, easing stress on tender spots and anchoring you securely through explosive moves like jumps, loaded squats, and pressing overhead. Simply slip it on—no straps, snaps, or closures needed—so you stay comfortable and free from hardware pressing into skin.

Shoppers consistently praise the support and snug, secure feel at sizes S–M. Please note: this design fits snugger than typical—going up a size works well if you want less compression or sit between standard sizes.

Offered in multiple shades. Sizing: S, M, L, XL.

Key features:

  • Cross-back strap system with load-balancing for even pressure
  • Nylon-spandex knit with four-way stretch and dimensional stability
  • Ventilating, sweat-managing material for any intensity level
  • Slip-on fit with no straps or wires—zero hardware
  • Snug compression—fits small, try a larger size for less snugness
  • Free from hazardous substances—safe for delicate or reactive skin
  • Works for gym, CrossFit, yoga, Pilates, and full-body training
  • Range of shades available, S through XL

What Ambar girls said

Worth buying again

The fit is flattering, the fabric feels premium, and there are no visible lines at all. I already want to order another pack.

Exactly what I needed

Finally a thong that feels breathable and truly invisible. The front coverage is better than anything else I've tried.

So comfortable all day

I wore these from morning meetings to an evening workout and never had to adjust once. They stay smooth under leggings and jeans.

Absolutely Amazing!

The comfort and fit are incomparable. I didn't realize what I was missing until I tried these. A must-have for every wardrobe.

Incredible quality

The material is premium and the fit is spot on. It's thin enough to be discreet but sturdy enough to do the job. I'm definitely ordering more colors.

Total confidence boost

I was skeptical at first, but it works exactly as described. No more worrying about 'camel toe' issues. It feels secure and stays in place all day.

Perfect for tight dresses

I wore this under a silk slip dress and you couldn't see a single line. It smooths everything out perfectly without being uncomfortable. Truly invisible!

A game changer for the gym!

I finally found the solution for my light-colored leggings. It's completely invisible and gives me so much confidence during my workouts. The fabric is incredibly soft!
