Heavy Down And Expidition Jackets
I tried a few down heavy down jackets and this is what I recommend:
The Valandre has a no stick zipper, it’s simply amazing! There first version had a hood that was too small to go over a helmet. I am not sure if they fixed it or not yet. But if you do not need a helmet I can recommend this as the best jacket.

If you need a good hood that will go over your helmet, but don’t care about the zipper getting stuck I would suggest the following Rab jackets. Anything too much thinner that this Neutrion, or without a hood isn’t worth it. , And anything thicker then the 7000 is too heavy for low altitude climbing. I am referring to the 8000.
If you really have to get something thin, this is the jacket I like, the small baffles and color make it a great jacket.
