Double checking my down parka purchase

I have been looking for a new down parka and think I may have fond it in the Montbell Frost LIne Parka and was wondering if I have made the right choice and would like a little help.

One of the things I wanted was for the parka to be big enough for my 6’5” 235# frame and I think the XXL will be.

I also wanted the jacket to be box baffled. I know Richard Nisley says that the construction doesn’t matter until you get to about 9oz of down but I know I feel a lot warmer in box baffled jackets versus sewn through ones when they are about the same amount of down added.

I did think about the Mirage also but it has less down and a thinner outer shell. I will be using this jacket while hiking/camping and around town also so I thought the 30d vs 7d was a much better choice. Richard also says that 10d is needed to make a jacket ‘windproof’ and since the only outer jacket I could wear over an XXL parka is a DriDucks XXL rain jacket because it is the only one big enough, I thought it was better to go with the 30d for that reason also. They also don’t have it in XXL. I thought about the Permafrost Parka also but was wary because of the Gore Windstopper material not breathing that much possibly and they also did not have it in XXL. The DWR on each jacket would probably be the same, correct

One thing I would have liked was hydrophobic down but isn’t there a wash in treatment for that also?

And the price of $220 seemed very good.

Please poke holes in this and suggest anything else I should have looked at. Thanks.
