Side-Open Mesh Racerback Binder - Black

Need a high-compression chest binder that you don’t have to pull on? Our Side-Open Mesh Racerback Binder offers one of our strongest binds, with the added convenience of a hook-and-eye side closure. It's a favourite for people with limited shoulder mobility, anyone who finds pull-on binders difficult, and those with a larger chest who need a closer, more adjustable fit.

Designed for trans men, non-binary people, and anyone looking for a safe, comfortable chest binder, this style combines our signature Powermesh with a racerback design that distributes pressure more evenly across your shoulders. The adjustable side closure lets you easily put on this binder, giving you a snug fit around your ribs without compromising comfort.

We build our binders differently for your safety! Unlike traditional chest binders with rigid front panels, our binders are designed with stretch throughout the entire garment. This helps your chest expand naturally as you breathe and move, letting you bind tightly without feeling restricted or causing pain. It also creates a more natural-looking, “masculinized” chest, rather than simply flattening everything into a straight line.

Because the mesh fabric is semi-sheer, this compression binder is designed to be worn as an underlayer.

High Compression Without Sacrificing Comfort

Two layers of our signature Powermesh create firm, even compression while staying breathable enough for comfortable all-day wear. The lightweight mesh increases airflow to help keep you cooler than many traditional binders with non-breathable front panels, while the seamless construction helps reduce rubbing and pinching.

The racerback straps help distribute pressure evenly across your upper back and shoulders, while the hook-and-eye side closure makes getting dressed easier and allows for a more customized fit, especially for larger chests.
