climbed Ice with this coat quite a few times this winter. and I love it. didn't get overheated on approachesand kept me dry on a climb that litterally was raining down on us. I didn't even think about getting wet. plus add in the carzy psycho winds from the chinook (only time I've seen ice fall up) didn't even feel ANY wind coming through. TWO thumbs WAYYYYYYY up on this. Now I can't wait to try the Ice Floe Jacket.

Ok I'm a bit biased here (montrail gave me the set-up for free for some pics that I did with 'em...sorry about the spray)

I took these out in the Canadian Rockies in Jan. this year. The first day out it was around -28C (that's as far down as the mercury would go so I have no Idea just how cold it actually was) sure my feet were chilly, but my buddy was wearing a pair of plastics and his feet were cold too . after I got moving they warmed up and I didn't have too much problem with 'em.
They work great, I can walk freely in them on approaches, Hell I can even drive in them if you can believe that... then when I get to the ice, I step into the crampons and the whole boot locks down solid, to provide a very stable platform to climb.
I've had these things on WI4- WI6+ and M4-M8+ and as always they feel as much as my climbing shoes would feel if they had a bunch of spikes attached to them.
I've been a major advocate of plastic boots for the last 7 years of ice climbing, but these just feel amazing...and at only 2 Lbs well...
The only concern that I have with them is the slots that the crampons are attached to in the sole. If anything happens to them ie. bend, crack, break etc, then how are they going to be replaced? they're moulded right into the sole of the boot. Also walking on rocks can be a bit tricky if you happen to step right on the tangs in the sole. it takes a little getting used to them but once you do...man oh man you will be a changed person

I've been using these tools since they first came on the market. sure they cost a lot of money to buy at first, but I knew that I wouldn't have to buy another set of tools for a long time. these things excell greatly on steel ice and are amazing on mixed climbs, because they are so well balanced.
The only problem I've found with them is that they don't really like low end ice (read WI 2). I don't know why it is. it might be the aggresive pick angle or something. However on that note, if you're going to cpend the money on these tools then chances are you are upgrading from a previous pair and are looking to get confidence on steep ice.
