It looks really nice, lots of good features, a tiny bit on the heavy side though. It says it has an interior pocket for Nalgene-type bottles, lol! That means you can keep your water inside your jacket... fun idea.

I've seen this jacket as low as 140 $USD over the web while searching for reviews so I would be hesitant to pay the 300 $CAD Altitude Sports want for it.

If you aren't in a hurry to make your purchase, you could wait a bit and try to see what are people's opinion on the new Gore-tex Pro Shell thing. If it's that amazing, you might be better off buying one of these for roughly 100 $ more than the Exposure II since this kind of jacket really is an investment and should give you years of reliable service. According to what i've read, Pro Shell is supposed to be the next big thing in hard-shell technology. MEC sell two Pro Shell models (well, two for men and two for women) priced around 400 $CAD.

I'll take a look at them next time I go.

Coming back to the MH Exposure II though, I think it would be a really good choice!
