Like I said, it's the only jacket I wear, and I live in the same climate as you, except your winters are worse. It has a removable liner that is quite warm. It has vents in the chest and arms for when it's really hot. Has good protection. AND I think it looks great. I highly recommend it.Wow lots of great replies, lots to think about, thank you! Since the Joe rocket atomic 4.0 is one I've had my eye on .. How is it?
You can definitely get the Atomic 4.0 in Canada, I think it's just one of the previous generations of the jacket. I've seen it on a lot of sites. However the site that has the cheapest combination of shipping and taxes (GPbikes.com for me) doesn't carry it. That's fine though, the Atomic 11 and Phoenix 11 look pretty good and they're available for $179.I don't think you can get an Atomic 4.0 in Canada. I bought mine in NY when I was there. In Canada, it's the Atomic 11.0 and it's different. Might be as good. I know it has YKK zippers, which are a lot better than the ones on the 4.0.
I'm a little over 6'1" and 190. The large is perfect for me.
