Review on CANWAY Double Sleeping Bag With 2 Pillows - Lightweight, Waterproof, And Spacious 2-Person Sleeping Bag For Camping, Backpacking, And Hiking - Ideal For Adults, Teens, And Couples - Queen Size XL by Dewitt Bhattacharya

I bought this full size sleeping bag because I needed to be able to fit more downy blankets inside it for warmth when I camp in 20°F or below weather, with or without a tent heater. My mummy bag is warm, but when I need more, I also need wiggle room and the mummy bag is too confining. Opened up, I can put it in this huge sleeping bag, just for myself.In the summertime having a bag that zips apart and back together for 1 or 2 people is really nice.****°My real qualm here is just that at the bottom center of the bag where the zippers top and bottom come together, there is a gaping 2.5" hole! It is impossible to fill it, and for a sleeping bag meant to keep you very warm, having a HOLE down at your toes is just not cool at all. Freezing, more like. It is like getting a super duper thick down coat, waterproof windproof, etc., only to have a warm hood snap on so that that the holes between the snaps allow the freezing wind in to blow out any warm air needed to stay in. Total oxy-purpose. I make sure mine have been sewn on or I sew them in myself.Outside of that, I ordered the black outer and blue flannel inner pattern, and it is very comfy.This sleeping bag is NOT super warm on its own, you do need something inside or on top if it is very cold. Just being honest. One cannot assume two people will be inside a sleeping bag to ensure a higher sleeping body temperature, but that is what was advertised.It is lightweight for winter, in-between for fall, and super warm for summertime.I was warm in this in the fall of 40°F at night, but do not think it is extremely warm and heavy for very cold temperatures. You will be putting another blanket inside with you, especially if it is really cold (15°F for me and I was alone), I also had my down coat on. It is warm, just not for very low temps on its own.Overall, a great sleeping bag!
