Big, thick and warm!
[This review was collected as part of a promotion.] I'm 6'4" so I always have a hard time finding camping equipment that fits me. Enter: this big beautiful sleeping bag by Coleman. This thing is HUGE! I'm a skinny tall guy, but this sleeping bag could fit almost two of me! It's really soft and plush which will also be really helpful for those nights where my boney hips find the ground and I pull the all night rotisserie chicken sleep... the one where you constantly rotate to take the pressure off ground.
I haven't had a chance to use this in its rated 20 degree environment, but I can tell it'll keep me plenty warm. I also love that it's got a hood that will keep my head warm or act as a little pillow. It also has this great foot vent for those of us that get a little claustrophobic. It even comes with a cool compression bag that cinches it down tight and compact.
The only potential drawback would be that I don't think it would be a great long distance hiking sleeping bag. I haven't done the multi-day, multi-mile, pack-in, pack-out type of camping, but I imagine this thing would get heavy after a while of carrying it. Don't get me wrong, I could totally bring this thing on a couple mile hike to camp for the night, but I don't think it's for those intense hikers that file down their toothbrush to reduce pack weight. Another word of warning: I tried to rip off the huge tag at the bottom of the sleeping bag and ended up ripping the stitching at the foot of the bag. Either cut it or get good at sewing.
For my needs, this is the best sleeping bag I have ever owned and fits tall guys perfectly.

Great sleeping bag
[This review was collected as part of a promotion.] This sleeping bag is awesome. The bag is plenty big enough so you have room to move and don’t feel like you can’t move once you zip it up. The sleeping bag is plenty warm enough so you don’t need anything else with the sleeping bag. It comes with a neat hood also if you are where it is freezing.

Love this thing
[This review was collected as part of a promotion.] I absolutely love the Big Bay Sleeping Bag! It is comfortable and very easy to use. Perfect for camping or just making a make shift bed in the house when company is over. I would definitely get another one if the need arises to have more than one sleeping bag.

LOVE IT
[This review was collected as part of a promotion.] This big bay sleeping bag is comfortable, the length is long and has a place to put your pillow and extra clothes if wanted. It is easy to put the sleeping bag back in the bag up for travel and it compress to a small bag.

Durable
[This review was collected as part of a promotion.] This sleeping bag is great for the extra cold nights and it has lots of room to toss and turn. The zipper is extremely smooth and does not get stuck at all. I would definitely recommend this sleeping bag.

Subzero weather approved
Bought this for my brother who loves camping, he does hot and cold weather. This was perfect for his last camping trip outdoors in the frigid cold. It was so functional and easy to maintain.
