Great bag
This performs great. It kept me warm with plenty of room. Fits perfectly inside a two person tent. I was disappointed it has a bed sheet like material on the inside so the bottom of the bag is not like the top. This forces you to use the Big Agnes double wide sleeping pad since it is not a stand alone bag. Maybe it's my fault, but I wish I knew I had to have the pad to go with it, fortunately I bought it too.
Fits my Exped Megamat Duo and Feels Like A Comfy Quilt
I have been looking for a double sleeping pad that will attach well to my exped megamat duo. This sleeping bag fulfills that function. I love the pillow barn feature of this bag that keeps our pillows in place. What really stands out for me are the draft collars and tubes. I always struggled to stay warm in our previous teton evergreen double bag due to cold air always getting in, that is not the case with this bag. I can pull the top of the bag up to my neck just like I'm sleeping with a quilt. It is also very very roomy, especially in the footbox. My partner is a hot sleeper and does not like feeling constricted when he sleeps and he is very comfortable in this bag. My only nitpick is that I wish the lining of the bag was a bit softer, I found it to be slightly scratchy - hoping it will soften up a bit with use/washing. I will also say this is a car camping bag, it doesn't pack down small - if that's a concern I'd recommend going with the down king Solomon version instead. All in all a wonderful bag from a great company.
Dialed in sleep system!
I'm new to matched accessory systems like this bag that require a pad underneath to work. But assuming you are always going to be using a pad, this method keeps things simple. No more bag sliding off the pad in the middle of the night!
Most comfortable sleeping bag!
The fabric on the interior of the bag is soooo comfy. It was super warm as well and perfect for the spring weather. Fit perfect on the Captain Comfort.
So good in cooler weather!
I used this bag snow camping in Mammoth Lakes and it was AMAZING. Super comfy and roomy for two of us, really easy to set up too. Highly recommend!
Dream Island Review
We have yet to use the bag out in the wild, but it seems like it is going to be fantastic. Very pleased
It was a Dream!
What a dream, it was like being on an Island…. In a good way!
