My Jofa 5090 shins are over 20 years old. I've sold two sets of back up pairs because I don't think I'll ever get to them. The next oldest piece of gear I have is three years old. The shins just keep on trucking.
My SG 3175's have about 15 years on them and I bought them used. I'm 5' 11" 270 and they've protected my fat rectum outstandingly. I love the Jofa stuff!
I'm also of Swedish Heritage so I gotta wear it but I've been very happy with it
