By far the most popular part of the series was Dallas' flag-based jersey concepts for Finland, Sweden and Norway. Now he's tackling Canada with the same principle in mind.

White in the middle with a red maple leaf (in the form of the classic Team Canada crest) and red sleeves to mimic the red stripes on either side. He's also put the Canadian flag itself on the sleeves.

Here's another Canadian concept, this time from Connor. The first thing I noticed was the merging of two classic sweaters — those belonging to the oldest Canadian NHL franchises, the Canadiens and Maple Leafs.

Obviously, the maple leaf on the crest belongs to Toronto and the striping across the chest comes direct from Montreal. Aside from that, it's not a bad look. Just needs to be a little more original.

I don't know when was the last time Portugal sent a hockey team to the Olympics (if ever), but I'm sure it wasn't recently. Still, Jason has sent in this Portuguese sweater for our enjoyment.

Another nation not seeing ice hockey action in Vancouver was South Korea. But why should that stop Ethan? Here is his attempt. It's a little busy, but definitely one of a kind.

Now we finish where we started — Team USA. Matt submitted this concept. I actually like it better than the current blue United States jersey. That one's a little dark. At least this has a lot of white and red in it.

There's no question in my mind that the Senators need to wear something like this when they eventually get selected for the outdoor game. Tyler's done a great job with this concept.

But his Capitals jersey is more of a Frankenstein creation than anything else. It seems he's literally taken element from every past Caps uniform and injected the Weagle. It's not terrible, but I think the stars are a bit distracting. Might be different on the ice.

If it's simplicity the Sens would like in a Winter Classic sweater, Tyler's may be the right look. But if it's true vintage they want, look no further than Drew's concept. I didn't like the crazy stripes when Montreal did it, but that might've been because the blue threw it off. Maybe the Sens could do it better in black.

Drew also threw in a couple of logos, including a simplified version of the old primary mark along with a new heritage mark to go with that jersey.

The Caps' owner may have recently nixed plans for an actual third jersey, but that doesn't mean concept versions can't live on here at Icethetics. Rather than incorporating the Weagle, which many have done (because of its awesomeness), Mike opted for a simple color reversal. Blue jersey, red logo. Not sure about the number being on the front though. We have enough to read there as it is.

Brad went the more traditional route with his third, but the key in this concept are the home and road jerseys. Check out the stars on the shoulders! That jersey belongs on a bit marquee sign, rather than a hockey player.

And if that logo looks familiar to you, it comes from the Capitals' old primary logo from the late '90s.

And lest we leave Canada out of the Winter Classic one more time, Ryan Haslett has put together this 2011 concept for a match-up between the Flames and Canucks in Calgary. You don't get any more classic with a Flames jersey.

However, I'm not sure it's the best idea to go with a Canucks jersey from the era in which they wore the same colors as Calgary. For the Canucks, there'd be no choice but to go back to the 1970s and the classic stick-in-rink log.

The last three Olympic Spirit posts have opened with a Team USA concept. That's not really fair is it? So here's John's attempt at jerseys for Canada. And yes, that is the Toronto maple leaf in red on the front of the home and road jerseys.

The alternate design, which kind of makes me think of the Devils, features the Canadian coat of arms. A nice effort, but I think one of the keys to the maple leaf on the Canada jersey is that it keeps you from having to spell out Canada at the same time.

Now we can get to the United States. Jack put together these simple but bold sweaters. That is a lot striping going on there on the sleeves. Not bad at all.

Here's a new look for Norway. John's replaced the traditional blue on the flag with a powder blue more reminiscent of the Penguins' throwback third. He's also got some interesting striping on the shoulders of that blue jersey.

Howie's back with a new look for the Swiss. He's added black and put the white cross front and center. Too much?

John has one more concept to share — for a nation that's never had an ice hockey team. Go Jamaica!

In the previous post, Glen had a very sharp white Team USA jersey. This is the blue one that completes the set. Not too bad. But I think with a crest that simple, the striping could be even simpler as well.

That brings us to Evan's Team USA concept, which employs the same ghosted effect seen on some of the jerseys in this year's tournament. I'm really liking the letters in red on this one. Seems way better than the current dark jersey, but not that much is really different.

The rest of today's concepts take us to Scandinavia. Here, Matt simplifies Sweden's jerseys and gives them a white one for a change. But personally, I've always been more a fan of the blue jerseys. And technically, white isn't one of their colors. Still, a great effort.

Dallas is trying something completely different with some of the teams that have simple flags. Here, he's adapted the cross on Finland's flag to stretch across the entire front of the jersey...

...and he's also done the same for Norway. Nice to see the polar bear make a return. What do you guys think of these?

Glen put together this blast from the past. Call me crazy, but this would be an awesome alternate jersey. Much better than the U.S.'s New York Rangers-based third. Plus, that's just a great all around crest. Where has it been all these years?

While we're on the United States, Matt is looking for a return to something a little more recent. Personally, I think USA Hockey needs a new logo.

Jared has put together concepts for several countries, including this Canadian one I really like. The black goes away, as it should, and another shade of red is added for contrast. I'm not sure so about the alternate jersey. May be a little too red. That's Russian territory, right?

Now, I take back what I said yesterday about Elias' Swiss design. Nothing against it, but this is just too cool. At first glance, it may seem plain — which is what I accused the current Swiss jerseys of being — but really take another look. That's just a really sharp design.

The only one of Jared's concepts I'm not crazy about is this one. Sweden arguably has the best jerseys in this year's tournament, but I feel like this re-imagining takes away from that.
