Many sleeping bags are rated for temperature by an independent testing protocol, the European Norm (EN) 13537. Each bag gets two ratings: a Comfort rating and Lower Limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average woman (or "cold sleeper") comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep an average man (or "warm sleeper") comfortable. Everyone's body and sleep comfort is different, so EN Ratings are merely a guideline to help you compare products.

Rated 5 out of 5 by from Everything I Ever Wanted! I researched this bag last year but was hesitant to buy it because I couldn't find many reviews. I pulled the trigger last week and just used it for 3 nights near the San Rafael Swell - it's AMAZING! I've always been a side sleeper and found mummy bags to not only restrict my movement, but also my breathing and heat regulation. I feel that most sleeping bag cinch-able hoods function like a blow hole - you can only breathe straight up, the cord rubs on your nose, your eyes are covered if you pull it tight and if you turn your head at all the inside goes damp. Yuck. The Celesta's hood is sort of shaped like a crescent, even when pulled tighter, and the blanket-like fold over lets you keep all of your core warmth in without covering your face. I also feel the shape of this bag is MADE for women with chilly appendages. I understand the concept behind body heat and space for thermoregulation, but I've always found cutting my cold toes off from the furnace of my core greatly prolongs their warming. The curvy shape of this bag allows the heat from my torso to fill the whole space without restricting internal circulation below the hips (like almost every other sleeping bag out there). For reference, the overnight temps I used this bag in were between 35 and 55 degrees, I sleep in next-to-skin base layers and socks, my pad is 3 inches thick, I slept on the ground the first night and inside our Half Dome the other two. I did wake up hot each night in the tent.

How small do they get when you pack them away? I'm about to Hike the AT, and I'm a huge side sleeper and want to make sure that this would be the right choice.

With a compression sack, you can get the Celesta 25 Sleeping Bag compressed to over half the stuff sack size (18 x10 inches).

The description says 25 degrees but the label on the bag says 35? Which is it and or what does this mean??

Asked by: jenjenmtns
The Celesta 25 Sleeping Bag is a 25 degree Fahrenheit rated bag. One of our pictures is showing the stuff sack for a different version of this sleeping bag. Thank you for bringing this inaccuracy to our attention. We will update the information on as soon as possible.

How well does this bag roll up. Is it compact?

Asked by: kfogg
This sleeping bag has very compressible synthetic insulation and can compress down to approximately half its stuff size (18 x 10 inches).
