In reply to elephant0907:
I've got an Alpine 40, I don't rate it.
After a season's use it looks a bit tired, some of the seams have started to bulge and I don't see it lasting more than a couple of years.
I personally find the roll top a bit of a scutter, that's probably personal though. I also don't like the detachable lid but again that may be personal...
The zip on the lid is too small.
The axe and crampon attachments are a bit close together and it can be difficult to get your crampons attached to the bungee if you have your axes on already, minor point but sometimes quite annoying.
Positive points are that it's very weatherproof and comfortable to carry, I wouldn't buy it again though.
