I'm developing a premium activewear brand with a focus on a sleek all-black design. I'm searching for a reliable manufacturing partner with expertise in high-quality gymwear. Key features include soft, performance fabric with a matte finish, an athletic fit, and minimal branding, along with potential options for laser-cut ventilation and silicone logos. Please share your experience in premium activewear, MOQ details, sample pricing and lead times, and available black fabric options. It would also be great if you could provide visuals of your best black fabrics in natural light. Looking forward to your insights!
