The Patrol Shelter is the white cuben. With MLD stuff sack and around 45 feet of guyline, it weighs app. 9.5 ounces.
The bivy is black. I haven't weighed it, can tonight after work, but on the MLD site (Ron's known for being quite close with his weight listings), it's listed at 10 oz for the 2010 version, which is slighter bigger than the 2009 version (maybe an ounce or less difference I would think).
