I use their PCT 1 which I really like. It's a full pound heavier, but it's double-walled, has a few extra sq.ft. of floorspace and is a bit cheaper. It has a greenish outer layer, though the website shows grey (mine is a couple years old).

I also use a standard bike cover to keep the dew or an overnight rain off the bike (and that nice, leather Brooks saddle!) I wrap it around my tent and Thermorest before strapping the bundle across the rear rack, so it does double-duty keeping the wet off my sleeping stuff while riding.
