Well, if you were in Tokyo, there is usually a shop within walking distance of eachother that usually caters to Nova needs. Even for the buff ones like you.
As for Eufiber, I usually don't use it for under-garments. It makes a good coat or rain cloak when I need it.
I can see why it's so popular. It's just everything you want it to be.
