Incredibly light and small for the size of tent it is - I researched lots and it's the lightest one I could find. Enough space to line up bits and bobs beside your sleeping mat and a bit more space outside the inner. Don't know exactly where I'd put a 65L pack though... I'll have to work that one out. The outer isn't that well ventilated so there was lots of condensation in the morning, but both inner and outer are waterproof, so I didn't really mind as this happens to all tents. The highest point in the tent was enough to sit, but you had to slouch a little, you can't sit up cross legged, so not so great if planning on spending long periods of time in there, but I was looking for a backpacking tent, not a camping or festival tent, so overall I'm very happy with it.
