What Is This

Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. Unisex sleeping bags list the Lower Limit which is the lowest temperature rating that an average male sleeper would be comfortable in.  Our women’s sleeping bags list the Comfort Limit, which is the lowest temperature rating an average female sleeper should be comfortable. The comfort and lower limit temperature ratings are listed in the features table on the product page. 

For example, a unisex sleeping bag that shows a lower limit of 23ºF means a man should be comfortable down to air temperatures of 23ºF while a woman would be comfortable down to the air temperature of 30ºF, the comfort limit. Men and women should always sleep in a layer of long underwear and use a sleeping mat.

Here’s a basic categorization of appropriate use, based on temperatures:
Summer:   >+35ºF
3-Season:   +10 to +35ºF
Winter:   <10ºF

There’s a huge variety of factors that can impact sleeping bag warmth, so these ratings are not guarantees. We always recommend choosing a bag that is a few degrees colder than you plan on going out in (choosing a 23ºF bag for 27ºF nights). If you have any questions about which temperature you should select, or how to improve your warmth in a sleep system, reach out to us on our contact page any time.

The Women's Latitude™ Series of down sleeping bags have been designed especially for female adventurers. Just like the Women's Trek™ & Women's Talus™, they're filled with more down strategically dispersed in the torso and foot areas, the hip area is roomier, and we use a layer of Thermolite® in the lower two baffles of the foot box, to keep ankles and feet warm. Filled with 750+ loft RDS certified ULTRADRY Down™, this range incorporates a full-length draft tube and neck collar for maximum warmth retention. It's a versatile tapered rectangular shape making it perfect for travel, backpacking, hiking and camping adventures in milder temperatures.
