A Pace fleece that I bought in '94, still going strong for riding, plus walking and general mooching about. Colour scheme is a tad retro (grey fleece with turquoise / blue highlighting) but it works so well I'll never get rid of it.
Got a pair of '92 Nike Poohbah shoes (saw a pic of Tomac wearing them in MBUK and HAD to have some..) still in one piece. Only wear them occasionally for old time's sake.
Also have a pair of '95 Oakley M frames, frames have been replaced once about 10 years ago, and have a small crack in them now, but still work well.
Quite lot of my road kit dates back to the '90s.
