This bag is not big enough for a 6ft 3in 300 pound man. It is like being in a cocoon, can not move. It is warm simply not big enough. While this bag says you can zip two together, you can not.
This bag is bulky but okay for car camping. It is very roomy, warm and comfortable for temperature above 40F. We experience freezing temperature during our last camping trip and it was COLD! The 0 degree rating is definitely not true based on our experience. You get what you pay for.
This Grizzly sleeping bag is good product. Had gone camping when the weather conditions changed and dropped down to 17 degrees that night in the tent. Kept us warm all night till the morning.
