"As soon as I heard we were playing in the Winter Classic and wearing the Blues original jerseys, I started thinking about designing the gear to match," Allen said. "I wanted something that would match the team's original colors and design while also having a clean and simple look. I think we achieved that."
Allen's mask for the Winter Classic was designed by Dennis Simone and painted by Jason Livery of Head Strong Grafx. It features a familiar shade of the team's original Blue as it's primary color. A thick gold trim that matches the color in the team's inaugural look runs through the outer edge, while each side features the iconic Gateway Arch under several large icicles. The mask also includes "ST. LOUIS" in a bold font across the top, several snowflakes, 2017 Bridgestone NHL Winter Classic logos on either side and the Blues 50 mark across the chin.
