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.

The Camp Self Inflating mat is a comfortable, durable option for the adventurer who wants quality and some serious bang for their buck. Utilizing the multi-function valve, this mat deflates quickly and easily, and there's no fighting re-inflation during pack up. Delta Core-V™ technology removes weight and bulk without compromising comfort and the durable face fabric will withstand some good tough adventuring. It's your back to basics, no-frills, sleeping mat that offers great comfort for backpacking and camping adventures.

Our blog post "Which Mat Should I Choose" has some helpful tips on picking the perfect sleeping mat. If you're looking for more comfort and a lower weight/packed size, check out the Comfort Light Self-Inflating Mat. For more comfort and less weight/volume the Comfort Light Air Mat might be the way to go.

Is the Camp Self-Inflating Sleeping Mat...?

  • Different from other entry-level self-inflating mats? Yes. The Delta Core-V technology reduces the weight and packed volume, and the mat is 1.5" thick (compared to 1" for similarly-priced alternatives).
  • Insulated well to protect me from the cold air and ground temps? Yes. The Camp Mat has a tested R-Value of 4.2 – suitable for use in all but the coldest weather.
  • Small enough when packed to use for backpacking? Perhaps. Conventional backpackers with 60+ Liter packs should have no issues stowing a Camp Mat. Weight/volume conscious backpackers may prefer an air mat – see above.

    Technical Features

    Delta Core-V­™

    In our lighter SI air mat models, we have removed 20% of the weight and bulk of the PU foam by using our vertical Delta Core-V™ method. We use sophisticated pressure mapping data that becomes the blueprint for our distinctive graduated core pattern.

    Where extra warmth and support is needed for the body contact areas - shoulders, hips, and feet - the core holes are smaller. In the less critical areas, we have removed more foam to minimize the weight and packed size. Delta Core-V™ technology is used in our Ultra Light SI and Camp Mat SI models.

    SI Multi-Function Valve

    We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.

    Extrusion Lamination

    Extrusion lamination is common in the medical and aeronautical industries, but Sea to Summit pioneered its use in outdoor products. Liquid Thermoplastic Urethane is applied to the face fabric through an extrusion head, where it bonds permanently. The result: Sea to Summit sleeping mats are more reliable and longer-lasting.

    Pillow Lock™ System

    The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),

    Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.

    All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.
