@Wormspice I’ve worn a friends in the past. Take your IH shirt or N1 size. Quality is great. Super over engineered. I have an IH n1 and wear it all the time. The mouton in the Dehen is much thicker and is best for colder temps. For me i like my IH for 30-45F. Dehen will be for below.
Came here to look at opinions on the Dehen vs IH N1. I have the Dehen and I really can't imagine a warmer jacket. The mouton lining is really thick and lush. The one thing I don't love about it is how sticky of a hand the waxed canvas is, I wish it was a bit drier. It's gotten a little better since last year when I purchased mine but it's still a total dust-and-hair magnet and I'm still waiting for it to get a little less tacky to the touch. I'd also say that because the lining is so insanely lux, the appearance of the collar is a little more "fancy" than I'd prefer when I'm wearing it out. All in all though, just one of the most overbuilt garments I own. Certainly a lifetime piece.
