If it has to do with Duck Hunting than there's definitely a BIG FAT size made!!!
On another site for Duck Hunting, the classified page is full of good equipment. Almost everytime something along the lines of clothing comes up that I might be interested in, it's in a size XXL or XXXL!!!
Maybe someday I'll be included in the group of Fat Slobs but not yet!
I just bought a new set of Hodgman Zipper front waders off that site in a size 10. The foot fits great but I could stand to add about 20 pounds! LOL!!
