This case study highlights one of the key products we developed at Saint Andro: the Oh Cool Compression Zip Top. The garment is a versatile, high-performance piece designed to balance function, comfort, and inclusivity. Inspired by sporty, outdoor lifestyles, it supports movement, sun protection, and thermal regulation, making it ideal for swimming, water sports, or casual wear. The focus here is on the design process, material exploration, and performance innovation that differentiate this top from conventional activewear.
