This sleeping bag is very warm and spacious. I'm not a small guy and i have plenty of room to move around in the bag without fear of getting tangled up in it!
Fleece lined for extra comfort on them cold nights. At each end of the bag, there are fabric 'envelopes' to attach to your bedchair and a adjustable quick realese strap across the middle of the bag to go under your bed furthermore keeping you on your bed and not on the floor!!
I have only used this in late summer so far, but i feel that it would be good even for winter use.
Have no reservations in buying this product - it is a quality item at a price thats right.....5 stars!!
