There was some confusion about this jersey design when I first tweeted it a few weeks ago. At the time, the source believed it to be the Avs' Stadium Series jersey based mostly on the Reebok template.

Turns out it's actually the team's new third jersey! It features a new number font and the Colorado state flag on the left shoulder. I've also refined the rendering of the crest in the above image.

The Avalanche are really starting to embrace their home state as the flag-style "C" will now be seen on all three primary jerseys.
