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 at which 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. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. Men and women should always sleep in a layer of long underwear and use a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.


Here’s a basic categorization of appropriate use, based on rated temperatures:
Summer:   >+35ºF / +3°C
3-Season:   +10 to +35ºF / -15° to 0°C
Winter:   <10ºF / -15°C


A huge variety of factors can impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag as one element in a sleep system which also includes an appropriately insulating sleeping pad and a liner. For instance - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C nights, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

If you are new to outdoor recreation, or you only camp occasionally, the Trailhead™ synthetic sleeping bag is a great value-oriented option. However, the modest price tag doesn’t mean we’ve cut corners on comfort and versatility. Like all Sea to Summit synthetic sleeping bags, the Trailhead™ utilizes WaveLoft™ construction to allow the insulation to expand out into air-trapping curves for maximum warmth.

As the temperature rises, the full-length zipper (which curves around through the foot box) allows you to sequentially increase ventilation to the point where the sleeping bag can be opened flat and used as a quilt.

The tapered-rectangular cut of the Trailhead™ gives you plenty of room to move, regardless of your sleeping position.

Is this synthetic sleeping bag…?

  • Warm enough for colder weather camping or travel? Yes. The WaveLoft™ insulation construction maximizes loft and results in a temperature rating of 20°F. Frequent cold-weather campers might look to the Traverse™ sleeping bag series. In cool or cold conditions, make sure you have a higher R-Value sleeping mat like the Comfort Light Insulated.

  • Suitable for summer temperatures? Yes. A full-length side zipper (with two zipper sliders) that extends through the foot box can be opened for ventilation or to turn the Trailhead into a fully-flat comforter in really warm weather.

  • Able to be zipped to another sleeping bag? No. If you are looking to couple your sleeping bag to a Sea to Summit Unisex model, the Traverse ™ sleeping bag series would be your synthetic-insulated choice
