I've been using a Sierra Designs Clip Flashlight 2 for many years as my backpacking tent. It was given to me as a gift by a close friend when I was his best man at his wedding.

It is relatvely light weight (very lightweight for its time) and has kept me dry in some substantial downpours. It was comfortable for me alone, and cozy when I had company.

Now that I have a family, I'm in the market for a more "family sized" tent. Most likely for car camping for the next few years.

I've used other Sierra Designs tents over the years and always been very happy with them.

Search their forums for R value and down compression.

Cool, thanks. I'll check it out.

Unless I get corralled into the hotelesque Family Tent, I'm sleeping in the hammock/tarp I made (and am continually changing each month). I haven't done a winter overnighter in it yet, but plan to soon.
