Hilleberg makes some very good quality 4-season tents: link . My dad has their solo Akto and likes it, but it needs a wide pitching area because of the way its guylines are set up. It's green and < 3 lbs.

I recently bought a Tarptent Double Rainbow but haven't tested it yet. It's very light, gray, and sleeps two. Their website says it's "3+" season, though I don't think I'd purposely take it up Mt. Mckinley or something. I've read a few reviews online and it seems to take wind alright, but I'd like to test that sometime.
