Whether it's for hype or not, I can't say. What limited runs do allow them to do is sell out quickly, therefore, reaffirming their belief that there is no need for them to mark stuff down.
Honestly, what they do makes sense.
Just received the slim dungs in 34. Perfect fit for the most part. A little baggy in the ass--but, waist, thighs and everywhere else fit well.
They are a little more tapered from the knee down compared to my OG's--and I wear a 33 in those.
For reference I typically wear a 32-33 in most denim.
Also, I agree--I think the patches look great. I've been going back and forth about having the patches removed on the Oatmeal tattersall because of the lightness of the fabric--but, for the heavier jackets I think it looks fantastic.
