Your Oldest Bit Of Outdoor Kit Still In Use?

I was asked the question recently.  This photo shows the answer.

That red neck-gaiter was called a 'snood' when i bought it at the (long gone) Survival Aids shop in Morland Cumbria.

I don't know exactly when I bought it, but it went with me on my first Nepal trip in 1986.

Thirty years ago!  Can you beat that? What's your oldest piece of hill kit still in use?

Some of the elasticity is gone so it doesn't spring back into shape.  There are also a few places where it's damaged.  But then,  I could say exactly the same about myself.
