    This is a bigger fit bag which is what I wanted. I am a stomach/side sleeper and this seems to be perfect for that. Just roomy enough for me to flail the legs a bit and move my arms inside the bag up to my head or down to my waist. The hood is fantastic. It fits like a hoody and is very comfortable. It allows you to change positions but never get tagled up in the bag. Good choice for restless sleepers.
    Some concerns are for starters the arm slots. Convenient when upright but vert difficult to use when lying flat. Similar to trying to take your shirt off while lying down. Not easy while sleeping. Anothe concern is the draft flaps. Very easy to knock out of primary position. On a very cold night this could be an issue to wake up to your shoulder freezing.
    I haven't tested in the field so I can't review it's temp rating. I mentioned the flaps being possible cold spots but unknown. I think if you want a super warm winter bag there is better but if you are like me and are a picky sleeper this is a good choice.
