Just want to make this clear: this is not a mummy bag, it has no hood for your head, and when the temperature drops, there is no good way to keep warm out from spilling out around your neck. I do have to say that the bag is made of high quality materials, and it worked very nicely when integrated with the Air Core mummy pad. In short, if you are claustrophobic and a warm sleeper, then you'll probably love this bag. If you are skinny and it's cold outside, you'll hate it.
For years I've just slept on foam insulites and, rightfully, I was always the first person getting my sore butt outta bed in the morning. With this pad, I actually want to sleep on it more than my bed, but my wife doesn't let me. Oh well. Great night's sleep in any position (I'm a side sleeper). No bottoming out. Yes, it does take about 13 breaths to fill it full (although can get by on 10), and the slight hiss of deflating is a bit of an affront to the back country, but I still highly recommended it.
This light get's the job done. It is small, light weight, and came with Energizers (and it's now only 16 bucks). The head band is made of quality elastic which has a bit of grip. The tilt mechanism locks solidly into place. I like that it only has two settings, high and low (who really needs a flashing SOS and strobe modes?).
The beam is not focused, so it casts bright light only about 30 feet. However, the light is great for up close work and general campsite lighting.
