which helly hansen parkas are the warmest? Any HH owners about?

I'm looking online and some of them look lovely but they don't have a warmest, warmer, warm rating like say landsend. Some say they are perfect for fall so that wouldn't be warm enough.

this coat is waterproof and insulated but it's hard to know how warm it would be

I like it though, it's so much less bulky than the NF arctic parka
