Does anyone make them anymore? Mine is from cabelas decades ago, and starting to wear out. I've never found anything else like it. Any secret sources?

I searched for some a while back and failed.

LL Bean has shirts that look like the old Worsterlon, but, by a different name.

Schnees makes the “Rifleman Shirt”. It is a “synthetic wool”. The problem is, the things are $100 plus...
