We understand that even with the same chest circumference, upper torso height and chest sagging can vary from person to person, causing the same size to feel different for each individual. To address this, we designed this binder with adjustable shoulder straps, making it adaptable to a wide range of chest shapes and sizes while offering customizable armpit coverage to meet unique preferences. • Compression Level: High • Adjustable shoulder straps: The 5-position adjustable hook enables the wearer to modify the strap length for a more personalized fit. • Racerback • By integrating a dense cotton lining with the outer fabric, the front panel of the chest binder effectively produces a substantial flattening effect. • Breathable and sweat-wicking high-stretch nylon fabric.  • Support for high-impact activities like soccer, running, skating, tennis, etc. • For enhanced quick drying and comfort, we suggest considering a chest binder from our dedicated SWIM collection, designed specifically for aquatic activities. • Outer: 75% Nylon, 25% Lycra; Lining: 100% Cotton
