100% organic cotton against the bust. No padding. No wire. Naturally breathable comfort.
Nothing feels better than cotton. Naturally soft, breathable, and effortlessly comfortable, the BIO-B1 Organic Cotton Wireless Bralette is designed for women who want the natural comfort of cotton with gentle everyday support.
Unlike most stretch cotton bralettes, the main fabric is 100% organic cotton with no elastane blended into the cotton itself.
The double-layer cups are molded directly in the cotton fabric, giving them their natural shape and structure without foam or added padding. Because the cotton contains no elastane, the molding process allows the cups to softly embrace and follow the natural shape of the breast.
The BIO-B1 offers a lighter, more relaxed feel while maintaining a beautifully shaped silhouette. The double-layer cotton construction provides natural coverage and gentle support without sacrificing softness or breathability.
The result is a bralette that feels light, natural, and incredibly comfortable against the skin. Perfect for everyday wear, lounging, travel, and anyone looking for an alternative to synthetic.
The fully adjustable straps allow you to customize the fit and support for all-day comfort.
Made using OEKO-TEX® approved materials, tested for harmful substances.
