If you carefully observe a Flyers game, you'll notice that the orange player numbers contrast with the orange of the rest of their jersey. Hockey Authentic, sourcing their material from the same supplier as the players, gets this detail right. It doesn't stand out too much in most of the photos provided by Hockey Authentic and by the reviewers, so to give a slightly different perspective for fullest possible color reference, I took a photograph in the daylight, with the numbers facing directly toward the sun. Between the brightness and the warmth of the light, this showcases the contrast at its highest.
People's mileage with the Flyers jerseys is varied, and it seems that they either love the design or find it ugly. Personally, I really like the jersey, with its bright orange and the way that the numbers overlap with it. When Philadelphia announced that they were changing the jerseys for the 2023-2024 season so that they would be burnt orange and that the arm numbers would be black (and also no longer overlap with the orange of the main body), I knew right away that I needed to get the previous season's version from H.A. before it was too late. If you're reading this sometime before the switch and share my design sentiments, go ahead and do the same.
