While a higher yarn count makes for a softer fabric, we are advised in suits not to go too high because the fabric won't be as durable. But in shirts is it the same way? Is a 180s shirt less durable than a 100s?
yes, as well, but yarn count is for shirts, so 80/1, 100/2 etc.
The super number Super 100s is not based on yarn count, but how fine the yarn is. Manton I believe had an excellent piece on this floating around somewhere.
cheap high thread count shirts wrinkle like crazy. I am wearing a nine year old prototype 160/2 and it performs as well, if not better as modern day 100/2 from most mills.
This is why some 100/2 from switzerland cost as much as some far eastern 140/2 or higher. The number in itself is not the only indicator of quality.
Putting a 500hp engine in to a mini doesn't necessarily make it a fast usable car.
