Anyone use the Mountain Hardwear 5th Dimension Sleeping Bag?

I have a Mountain Hardware sleeping bag but I cannot remember which model. I have had it a few years so they have probably changed the name anyway.
I bought it because when I went to Alaska the outfitter told me NOT to bring a down bag.
[I have a -30 below Marmount Mountain down bag.]

If a down bag gets wet it is useless, synthentic will still keep you warm.
My Mountain Hardware bag is made very well and of high quality. I have used it about 50 nights in Alaska and like it very well.
