The Moonstone Maxima is incredible. It is designed with extra room in the torso, so you don't feel so constricted when you cinch the top. The A/C liner is removable which makes the bag tolerable in warmer weather; without the liner the bag is rated at either -5 or +10 depending on how much fill you decide to sleep on. Moonstone makesa real quality bag: I sleep in some damn cold weather and that bag has never let me down.
