Bend, OR – April 16, 2024 – Branwyn Performance Innerwear, the only ethical, sustainable, and next-to-body Performance Innerwear made by and for active women, proudly unveils the Essential Racerback Bra, engineered with a seamless Merino construction to provide unparalleled comfort and support for women on the move. After two years of research and development, Branwyn is thrilled to expand its Essential line of Merino Wool Bras with its newest innovation in Performance Innerwear.

Crafted from Branwyn’s exclusive GLDNspun knit, the Essential Racerback Bra boasts 76 percent extra fine Merino wool content, making it the market leader in high-performance, seamless Merino bras. By utilizing state-of-the-art core Merino spinning technology with 14 percent nylon and 10 percent Spandex, the Essential Racerback bra mimics a second-skin feeling and ensures optimal breathability, odor resistance, and exceptional thermoregulation. Its body-mapped contours offer enhanced support and separation to reduce chafing, while the wide-knit bottom ensures the band stays in place. Shoulder straps with backset and flatlock seams are strategically designed for comfort, accommodating hydration packs, backpacks, and kid carriers. The bra also features side sleeves that allow for padding inserts for additional coverage (not included). The underwire-free pullover style and racerback design ensure freedom of movement, eliminating common discomforts like digging and rolling. Designed for moderate-impact activities, the Essential Racerback Bra offers greater compression than Branwyn’s Essential Bralette and Essential Busty Bra. It’s perfect for those on the go, whether in the mountains, at the gym, in the yoga studio, or navigating daily life. 

“Branwyn is proud to be at the cutting edge of BPA and PFAs free women’s high-performance innerwear, says Branwyn’s President Deanne Buck. “The launch of our Essential Racerback Bra introduces an entirely new category of moderate-impact sports bras that uniquely combines Merino and next-to-skin seamless construction. As we continue to innovate, we are committed to building on our foundation of developing products by and for active women that prioritize comfort, temperature regulation, anti-microbial properties, breathability, and overall benefit women’s health.”

Distinguished by its blend of state-of-the-art technology and eco-conscious practices, Branwyn’s Essential Racerback Bra also harnesses the power of ZQ, Oeko-Tex 100, and RWS-certified Merino wool. This ensures premium quality and underscores the brand’s dedication to environmental responsibility. As with all Branwyn Innerwear, the Essential Racerback Bra is made with Italian Santoni Seamless machines, an innovative production process that minimizes waste.
