@DrPat:

Definitely 3xl.  4xl if you want a looser fit or will use it for athletic activities.

thanks for this info.  im about to obliterate my credit card. i asked similar question for the new vest.  stick to UHF?

@DrPat:

I had a chance to try this one on.  I would definitely recommend sizing up one from your normal IH shirt size.

Right now I have a spread of Iron Heart shirts in XL to XXXL.  But Im consistent with XXL in UHF.  Do you think I should go XXXL in this parka? I know its opinions and recommendations at this point but they are appreciated.  I would mainly wear the jacket with a light undershirt and some IH long sleep top, denim or UHF

@alexpupin:

Crew,
I'd like to layer this vest under my size L Sateen M65.
I'm thinking UHF/heavy shirt (I wear XL) +  Vest + M65 (L, with enough room).

Should I go size L or M with the vest? I'd like it to fit snugly and tight.

Thanks in advance for any suggestion

I've got last year's vest in the same size as my UHFs.  I believe Giles also went with his UHF size.  I wouldn't want to size down in this since it's snug enough as it is.  Remember, this vest is puffy so it will fit tighter than non-puffy shirts and jackets.  Also, they run a bit short and sizing down could cause problems with the length.

Would you recommend the same size as UHF or up one?  I dont need more outerwear but this vest and street parka are calling my name!

@Giles:

I know that, what I was saying is there does not need to be if you know what size you are in a UHF, because you can see what others wear in this and in a UHF.  So if someone wears an L in this and an L in a UHF then its pretty reasonable to assume you would be the same in both too.

i totally get this now, went over my head.  i should look at how folks are adjusting their sizing for the jacket and make the same adjustments on my end.  shouldnt make a difference on the actual size, just know to go up or down or the same. sorry about that.  i need to go double check my UHFs, i think the westerns fit tighter on me than the workshirt.  thank you for your help.

We've updated the "See what the crew wear here" bullet.  So you can go look at that, then check what size they wear in other stuff, like UHF's

you all had someone else on this list that I used to use for comparison, he no longer is on the list.  i cant remember, Jack?  someone that used to fit a lot of stuff in XL.  i just dont know if I am an XL in this or XXL?  Depending on the IH jacket I am one of those two sizes.  but with this amount of insulation I dont know what to go with.  I cant risk ordering and it not fitting.

The point I was trying to make is that if John Doe wears the same size in a shirt and this jacket, then you will likely do the same, if John Doe wears an XL in a Ultra Heavy Flannel and an XXL in this, then you probably will too.

I typically wear XL in Ultra Heavy Flannel westerns (though I can squeeze into an L), and I wear an L in this jacket….

i totally understood, i was pointing out that there is no one on your list of folks that fits similar to me.  you did have someone else on your list before but I no longer see them listed.  do you have anyone in your team that wears XXL-XXXL in UHF?

Any sizing advice on this one? I wear XXL in UHF, maybe a little on the snug side with XXL. Ive checked the measurements on the jacket and i dont know how to compensate for all the insulation the jacket has.

The classic N1 deck jacket was first produced for the US Navy in the early 1940s. Much copied since then, it has become a true style icon in its own right. The Iron Heart version remains pretty true to the original jackets on the basis that "if it ain't broke, don't fix it". The one major, but unseen, change we have made is to add an additional interlining to increase wind resistance. A truly warm and great-looking winter jacket. For this years rendition we have added the interlining to the collar and tweaked the pocket placement very slightly.

Changes in bold from the OP. The other only other difference is a slightly different alpaca wool mix than previously

Thank you Alex.  One more question, I see other brands offer deck jackets with shearling instead of alpaca.  I dont know much of difference between the two as I have never seen shearling in person.  Which of the two is warmer?

@LewisStonehouse:

@bigwhat62 almost certainly a 29 if you bought it in summer, the 35 came out the end of October 21

you are probably right.  if we are looking at just timelines this makes sense.  i didnt know when the 35 came out for the first time.  if its initial release was this last fall then this 100% answers my question.

anybody know the big differences between the two?

i purchased a used black N1 this summer.  thing was pretty much new minus tags.  how can i tell if it is the IHM-35 or IHM-29?
