The Wintec waffle girths we had were made from vinyl
plastic. This is an important distinction. Vinyl plastic is, by
nature, hard. It is used to make the white drain pipes for homes. To
make it flexible for girths and other uses, the maker adds materials called
"plasticizers" to the vinyl. Over a period of time, sweat, heat, flexing
etc. tends to remove the plasticizers and the vinyl becomes brittle.
I found that after about 4 seasons I have to
replace Wintec girths because they are brittle and start to crack and
cause rubs.
I also wonder if some of the reports of "Neoprene"
causing reactions on some horses are actually the plasticizers leaching out of
vinyl girths.
