Second on the Outdoor Research gaiters. Mine are more like 20 years old. IIRC purchased them from REI.
Third here. Mine are at least 20 years old - probably closer to 25. I was wearing them long before any of the fancy Sitka, Kuiu, gear existed. It was wool pants with gaters back then. The gortex is a little worn out and so is the velcro, but I'm having a hard time swallowing the $85+ price tag on the new ones.
They are one of the best pieces of hunting clothing a guy can have. Not sure about the new brands, but you want the top cinch strap to be above the top of your calf muscle - almost right under the knee. Don't get the short ones.
