@Mustafa911 - "fade better" is a very personal opinion. Some people prefer the way IH denim fades, while some people may prefer the fades of a different brand. Even within the IH allotment of fabrics, each one has somewhat of a signature fade pattern, which some people have a preference of one over the other.
What makes this denim more expensive than other IH offerings is 1. The difficulty in making the material (cost to produce + how much is lost in the process) 2. How little of the material was made.
The more of a "bulk" order a company is able to make, it keeps the costs per (yard in this case) down comparatively. The Yenim (A play off the Japanese currency "Yen" and "Denim", since this product was created using the same pulp as used to make currency) had a lot of "loss" in production, thus very little was used in manufacturing.
Same idea is true for most clothing items, cars, etc.
If you get these, I hope you enjoy them!
If I am completely wrong, anyone feel free to correct me haha
