The Universidad Católica 2021 home kit comes with a pale navy blue base, contrasting to the more vibrant tone of last ye...ar's kit. Darker accents are seen at the neck and cuffs, where a short stripe of Umbro branding sits at the end. A subtle pattern showcasing trains (reference to their nickname "Trencito Azul", translated as "The Blue Little Train") together with Umbro diamonds appears at the front.
