The hood area has a drawstring that allows you to open it up prett good. I'm actually able to stick my arm up through and above my head if I wanted to. I also found that you don't have to put your head in the hood area. If you want you can put your feet in the box and use it like a regular TQ. It doesn't tuck well like that, but it works if you don't want to trap a lot of heat.
If you ain't havin' fun, you're doin' it wrong
