In reply to blackmountainbiker:
Berghaus 30L rucksack from 1982/3 is my normal bouldering/wall sac. Originally my wife's (funny how my sac was always much bigger on holiday) but she's not used it for over 20 years (far too scruffy amongst other reasons) 😁
Just re-read the OP, rucksack isn't really clothing (bivi bag?) but what the hell...
Actually I have a "fruit of the loom" T shirt that seems to have lasted 30 years, Xmas present from agency (Rullion) when I used to be a contractor. Scruffy but useful because it's longer than normal so tucks in well if it's that weeny bit colder.
