The supermega UL 2 is a well thought out light weight backpacking tent. I have used this tent almost a dozen times now and it has held up against southern Utah monsoon like downpours to uinta mountain rainy days. Clear nights with no rain fly are great if you want to get your star watch on as well.
If you are trekking solo this tent provides ample room for you and your gear. With a second person it is a tight fit, but not too uncomfortable. I prefer it when backpacking because of the 2.7 pounds it weighs and it takes up such a small amount of room in my pack.
My only complaint about this tent is the lack of headroom. I am 5' 11" and sitting up inside the tent is almost impossible with a 2nd person. When I am camping alone however, it is quite comfortable.
