EXTREMELY RARE.  Given out to only invited participants at the Xbox 360 Launch Party in Mojave Desert in November 2005.

Adidas sweater size: L 
Measurements: L27 W25

Baseball hat and beanie: One size fits all.

Baseball hat was signed by 2 people.  One of them was Cliff Blezinsky (aka Cliffy B)

All 3 items are in like new conditions, as they were maybe only worn a handful of times and some items maybe even never.
