Event Vest/T-Shirt

I don't usually favour the mid-range adidas vests as they're typically bulky and heavy. Of course the company makes very good ones as well but at RM160+ the ClimaCool vests are not what you'd call cheap. As I was scouring the Singapore Marathon site for their 2005 Runner's Event Handbook, I came across this picture of a girl wearing an adidas vest. It looks simple, nice (and I mean the vest!!!) and light. Hopefully the event tee will be likewise.
