While this is a bit on the heavy side ( 9lbs) it sets up very fast and can be opened to the fire if needed. I haven't been out in the rain with it, but being canvas, I am sure its OK, I still would tarp it though as wet canvas is a bugger to pack up.It did great this last week though as I was out hunting, and the Temperature dropped to -10 c both nights, so opening to the fire was very nice.
