i recently bought the IB-141 new, and also picked up an EB-140 second hand (although it was practically new) and i absolutely love the pair of them.
Both size 40, and i am usually a large in most iron heart shirts and jackets.
I especially find the colour of both jackets really beautiful, the green one has some real depth to it that is hard to see in photos.
The Eb 140 is also a bit thicker/heavier than the IB141, so is better if its a bit colder outside with the indigo more of a lighter, everyday jacket
