Maximum Airflow, Minimum Distraction

When the temperature rises, you need gear that helps you let off steam. Our Open Back Sports Bra is engineered to optimize body temperature regulation. By removing excess fabric from the back, we allow heat to escape freely from one of the body's highest sweat zones. This keeps you cooler and drier during intense sessions compared to traditional full-coverage backs. This functional design element also doubles as a major style statement, perfect for layering under one of our sheer or low-cut women's tank tops to showcase the details while you train.

Unrestricted Range of Motion

Restriction is the enemy of performance. The open back silhouette frees up your shoulder blades and spine, allowing for a completely natural range of motion. Whether you are reaching for a hold in climbing, twisting in pilates, or lifting overhead, these bras move with you, not against you. We use buttery-soft, four-way stretch fabrics that provide a secure, comfortable hold without digging in. For a sleek, aerodynamic look that matches this freedom, pair your bra with our sculpting Biker shorts.

Elevate Your Activewear Wardrobe

We believe that your workout gear should make you feel powerful and confident. The open back design adds a touch of elegance and edge to your rotation, proving that you don't have to sacrifice style for support. Available in a range of colors, these bras are the perfect starting point to build your own Matching workout sets. From the studio to the street, the modern aesthetic pairs effortlessly with high-waisted bottoms, making it a versatile piece you will reach for again and again.

FAQ

Yes, despite the minimal back coverage, our bras are engineered with a supportive underband and secure front straps to provide medium support suitable for cycling, gym training, and yoga.

Absolutely. Because there are no clasps, hooks, or bulky layers on the back, open back bras are often more comfortable for exercises where you are lying flat on your back, such as sit-ups or bench presses.

While many people do run in them, open back bras typically offer medium support. For high-impact running where bounce reduction is critical, we recommend checking out our specific Running sports bra collection.

An open back sports bra features a design that exposes part of the upper or mid back while maintaining full support through the band and front construction. The open-back design adds ventilation and a stylish detail that looks great worn on its own or under open-back tops.
Yes. The support comes from the band, front panels, and strap construction — not the back panel. Our open back bras provide medium support suitable for weight training, barre, pilates, cycling, and moderate cardio. The open design doesn't compromise support during these activities.
It's a great choice for hot yoga. The open back design increases airflow across your back, helping you stay cooler in heated studios. The moisture-wicking fabric handles heavy perspiration, and the medium support level is well-suited for yoga's range of motion.
Wear it on its own with high-waisted leggings or shorts for the gym. Layer under a loose tank or open-back top to show off the back detail. Pair with a cropped hoodie for a warm-up layer that you can peel off when your session heats up.
Yes. The open back design doesn't change the fit through the bust or band. Order your regular sports bra size. If you prefer a tighter, more compressive feel, stick with your standard size. For a slightly more relaxed fit as a standalone top, size up one.
