I have a new but without tags Spyder D30 armoured top, good for cross country, all mountain riding.
It is size medium. It is new I have only tried it on but I have had it two years thinking I would lose enough weight to fit it.....
Not happened 
You are welcome to inspect or pick up if you are in SW London.
Yours £60 (£200 new IIRC)
Just for those not aware, D30 is a flexible soft material that under a shock loading goes rigid so perfect for a top where you need to move around a lot but perhaps don't want rigid plastic armour.
