Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.

A unisex sleeping bag with 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. These ratings require 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.

A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - 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, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

The Basecamp™ Thermolite® synthetic sleeping bag is for those who preferred style of camping is returning to the same campsite each evening to a luxurious and versatile sleep system. Each side of the Basecamp has a full-length side zipper; a third zipper can be found in the foot box zipper. The result is unmatched ventilation and the ability to remove the entire top section to use as a quilt.

WaveLoft™ construction allows the Thermolite® insulation to expand out into air-trapping curves for maximum warmth, and the overall shape of the Basecamp allows you to sleep in any position you choose.

  • Warm enough for cool weather camping or travel? Yes. The quality insulation and technical construction keep you warm even on chilly nights. The Basecamp 10°F – paired with a high R-Value sleeping mat, like the Comfort Plus Insulated, would be warm enough for Spring through late Fall.

  • Suitable for summer temperatures? Yes. The full-length side zippers and foot box zipper can be opened for ventilation or to remove the upper section completely for use as a comforter in really warm weather. And – the main side zippers can be zipped to another Basecamp or many other Sea to Summit sleeping bags.
