Special thanks to Alex F. for getting the measurements I needed! Fits just how I like my truckers. Highly recommend this jacket to anyone on the fence.
PS @worn2fade I soaked two 526Ls both within the the recommended IH temp (30-40C) 1hr, then into the machine for a gentle wash on cold no spin. Both jackets .5 inches off the shoulders, 1 inch off the length sleeves/body. Chest shrinkage was minimal.
I'm finally getting my IH shirt fit down with a couple of hard misses and some special help from the IH crew. Sold those off and picked up this one and really dig the fit! It's ever so slightly snug in the chest and shoulders, but not restrictive or uncomfortable. Shoulders are the constant issue that I found I need to get dialed in with these shirts as they seem to run narrow. It's the perfect weight to wear under my type iii jacket. Glad I was able to find measurements on the 33 that worked because I was told no more from that line coming in 2025.
@Tobi I think the jacket looks perfect. It depends on what you like though. I personally like my trucker jackets to fit slim and hit at the waist or close to. I also don't like to wear bulky clothing underneath. If I want to layer, I layer a parka over the trucker. That's just what I prefer. This one runs pretty long in the torso, even longer than the other modified type iii's I've noticed. I was just in a similar situation with these jackets. I decided to size down because the body length was just too much. I was concerned with sleeve length as well because they hit right at the wrist and I think that's perfect, but was concerned about the creasing and it riding up. The IH crew assured me the sleeves would not come up much at all especially when the jacket wears in. The bit of natural stretching/relaxing offsets the creasing in the sleeves. Time will tell. I really like how mine is fitting now.
First pair of 21oz 888s and they're fantastic! I tried getting into the 777s and 666s, but they were incredibly tight on my legs. This cut feels much better. I had concerns that these would be too tight as well, but after a couple hours they have loosened up already and are very comfortable. Thanks again @Alex for the last minute fit advice!
A type iii in 18oz vintage fabric would be cool.
@Brandrea I agree with @Chibs. They're two different things. Do you want a jacket, shirt or both? The CPO is basically a denim jacket that looks like a shirt. If you already are wearing a denim jacket get the 33. I actually just picked one up. I was looking at picking up the 293, but it would never get worn because my 526L type iii jacket is getting the wear. The 33 works perfectly under the jacket. It's a lot lighter and more like a typical casual dress shirt. But if you need both, get both.
@FlavourFade It almost doesn't shrink at all. Trust me. Get the jacket measurements that are closest to your normal ones in a pre-shrunk. I've done it with this jacket twice. The first time I ordered it I took measurements bigger than I should have. I also soaked and washed that one at 40c and there was very minimal shrinkage, 1 inch still in the body and sleeves, minimal in chest and shoulders. The second time I took measurements that were all within .1-.2 inches of what I where in a pre-shrunk model and it was perfect. Like I said it will shrink 1 inch in the body and sleeves, very, very minimal shrinkage everywhere else. That's if you soak and wash it at 30c or less. Don't take the advice that you need to boil the jacket in the hottest water possible with the hope it will shrink to the fit you want. Stick to your measurements, wash 30c or less and you'll be golden.
@Graham thanks! I picked them up at Self Edge, SF. Easily the best damn jeans I've ever had. Thanks @RobeOfTheMagi 
@tenuin are these on new runs of shirts or old ones? My IHSH-33OD from the last run does not have this pocket spacing issue.
@northsouthdenimguy ok thanks for the clarification. I can see that clearly from the photo @FlavourFade posted.
@Gavin666 I can't tell what you're talking about from that photo.
@worn2fade I hear you on the length. That's one of the main reasons I bought another one and sized down. This jacket is very unforgiving in the length. I do really dig mine now though. I also have the LOD version and that hits me a little higher, right at the belt. I don't need another type iii, but if I did pick one up it would most certainly be an unmodified classic trucker.
Sounds good, thanks guys. 
How much does this one shrink after the first wash? I have the OD, but that one is pretty stable in terms of not shrinking I guess because of the OD.
@worn2fade I've had to buy and sell more than a few items to get a good fit. It's definitely trial and error. I'm not one of those that can fit any IH piece with ease, but when I do find something thats a fit it's worth the headache! Your jacket looks good on you though
