Is it possible to find 28oz wool?

[gunnarthefeisty]

I've been able to find some 32oz wool, some sources of 30 oz wool (unfortunately containing nylon), and some 26 oz (also containing nylon). I'm trying to get a vintage coat reproduced. Will I have to go with the extra-heavy 32oz, or will the 30oz with nylon hold up, and is there, out there somewhere, 28oz 100% wool? Thanks!
