Our women's Boylston Singlet goes above and beyond so you can get the most out of your run. Sweat-wicking technology helps keep you comfortable and dry, while reflective accents make you more visible in low-light conditions. It's one of our smartest designs yet — and one of our most stylish too. We made sure the cut was feminine (the racerback is cool and eye-catching) and chose vibrant colors that tie back to your favorite New Balance shoes.
