Honestly, the more I look at this Duck's third jersey, the more I like it. The things that do it for me is I love that old Ducks logo, one of the cooler "modern" logos to be created in the NHL.
Also, with the NHL's love for mundane, dark jersey colours, this orange actually looks like it could look really cool in real life.
What pulls it all together for me though is the no piping or weird vertical stripes, The horizontal stripes, give it a nice classic look while still being a neat, fresh design that pops.
I think they really nailed it with this one. But I guess seeing it in action will tell the whole story.
