This is the most spacious yet compact sleep bag that I have ever used and it fits in persons as good as 6 feet 6 inches and I really liked it for the reason how practical the sleeping bag design is. – The fabric material being nylon is quite smooth and comfortable and well stitched all around with nice zippers and straps engaged for a convenient operation and less hassle on opening up and packing it in. – It comes in a stuff bag that is easy to use, fit in the whole bag compressed and a laundry style mesh bag for easy carry on and safe storage. – Like a stuffed jacket, this has good amount of thickness that is adequate for such bags on all sides to give comfortable floor cushion and as well extra coziness and warmth. – Once got in fully, it should be good for sub-zero degree centigrade temperates as it was meant for 30 degree Fahrenheit which is -1 degree centigrade. -Another feature is that there are couple of straps on the packing bag which can be used to secure bag inside and also tied onto a backpack. – Works great for taller people and medium heights equally good so this is a one-size for any adult sleeping bag. – The zippers provided – longer one on left side for easy entry and exit and smaller length on right to gain space to adjust Some observations and improvements: – While it is not truly a con, It would have been great if the head side would have come with a wedge pillow stuffed in. For some reason, there is one rectangular stuffed cushion on chest side. – The zipper on both the sides need to be carefully pulled to avoid getting jammed with fabric enroute. This is Net-net, I would recommend this great looking hybrid sleeping bag to those everyone who go on campings, remote nightly stays and even household where winter storms and freezes are more common.
