They list the bag as 30 degrees comfort, but someone posted a pic of the bag and it’s labeled as 38 degrees comfort. I’ve found significant differences between a 30 degree bag and a 40 degree bag as it gets closer to 30 degrees
At 38 oz for a 40 degree bag, it becomes far less appealing. I have a MLD Spirit 38 bag (Apex insulation) that only weighs 19 oz, on top of that it has a poncho hole, so it can also be worn around camp or glassing.
