Rated 5 out of 5 by from Excellent Bag I have had this bag for over 1 year now and it has been to the deserts, the mountains and even windy islands. I naturally run cold, but this has kept me very warm down to 26 degrees. I am sure the temperature could have dropped some more and I'd still be comfortable. In December 2016, I camped in northern California during the heaviest rains the region has seen in years. The inside of the tent was cold and somewhat damp. The outside of the bag felt a little moist, but I was kept completely dry. Aired the bag out for a couple days afterwards to be safe, and it's completely fine. For reference, I'm 5'4" and approx 122 pounds and the bag size is perfect.

Rated 5 out of 5 by from Great sleeping bag! I've had this bag for about a year now and I love it! It's very warm and light. For it's maiden voyage I took it to over 9000ft in late June. Overnight the temperature dropped to below 25F and I was toasty warm. I actually had to sleep part of the night with one arm/shoulder hanging out of the bag. Everyone else was freezing...

Rated 5 out of 5 by from Cozy, Convenient to Carry Traded out my synthetic bag when I couldn't stay warm, and I am so happy with this one! I've had it for over a year and I couldn't be more pleased. It is lightweight, packs down small, and keeps me more than warm enough. Plus I love the color. Can't wait to use this bag for a long time.

How do I add the inflatable liner to this bag?

Asked by: marilyn
This bag does not come with an inflatable liner. If you are using a sleeping pad with this bag, you place the sleeping pad on the ground and the Heratio on top of it.
