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 Comfort Plus™ Insulated Sleeping Mat earned its Backpacker Editors' Choice award, 2015 for a combination of its Air Sprung Cell™ technology and dual layer comfort. With two separate layers of interlocking air chambers and our multi-function valve, the sleeper can fine-tune the top layer to perfection, and adjust the base layer to accommodate for rough terrain. The built-in redundancy is not to be taken lightly - if one side of the mat punctures, the other is still able to function until a repair is made. It's insulated with Thermolite® and Exkin Platinum® for great warmth.

Our blog post "Which Sleeping Mat to Choose" has some helpful tips on picking the perfect air sleeping mat (or why you might prefer a Self-Inflating sleeping mat).

IS THIS INSULATED AIR SLEEPING MAT…?

  • Warm enough for four-season use?  Yes. This air sleeping mat has a tested R-Value of 4.0 which is enough insulation for all but the coldest ground.

  • Really comfortable despite being 2.5” thick?  Yes. Thickness is not the key factor in an air sleeping mat; the number of points of suspension is. Your weight and contours rest on 548 individual air-filled springs (size Regular).

  • Easy to inflate?  Yes! The supplied stuff sack features an integrated Airstream Pump – just a couple of breaths will inflate the air sleeping mat. No dizziness for you, and practically no condensation moisture inside the air sleeping mat. Genius!

Features

  • R-Value of 4  is warm enough for all but the coldest ground. Click here to learn about the new ASTM R-Value test standard.
  • Exkin Platinum® fabric and THERMOLITE® insulation are combined to prevent heat loss. The dual-chamber design means no top-to-bottom air movement, which reduces warmth transfer.
  • Dual-Layer Air Sprung Cells provide more support, insulation and excellent comfort.
  • Quick and easy inflation, deflation and adjustment made possible by patent-pending multi-function valve and supplied Airstream Pump™/stuff sack.
  • Tough 30D / 40D face fabric with Sea to Summit’s liquid-extruded lamination is quiet, durable and extremely reliable.
  • PillowLock™ system to preventing your Aeros™ Pillow slipping.

Technical Features

Dual Layer Air Sprung Cells™

Air Sprung Cells™ are the core technology used in Sea to Summit Air Mats and are the reason you will sleep more comfortably on a Sea to Summit mat than on a conventional air pad. Inspired by the hundreds of springs found in a modern pocket sprung mattress, the hundreds of small interconnected chambers (called Air Sprung Cells™) perfectly support your weight and conform to your body contours.

The Comfort Plus series of mats has an internal layer of 40 Denier Nylon dividing the mat into an upper and a lower chamber. This allows the welds of the lower and upper cells to be offset throughout the entire mat, resulting in the greatest possible support and insulation, and a unique ability to fine-tune comfort. When on uneven terrain the bottom layer of the mat can be inflated to a high pressure as a barrier. The upper layer can then be adjusted - using the fine tune valve – for more comfort and softness.

This also ensures a level of built-in redundancy. If one layer becomes punctured, you can still get through the night with the other layer of the mattress intact.

Dual layer construction air mats are perfect for those looking for the ultimate in comfort and insulation, who are prepared to carry a few more ounces

Integrated AirStream™

The Airstream™ Pumpsack is Sea to Summit's big volume mattress pump which we've now integrated into the stuff sack of every Air Sprung Cell™ mat. The clever design opens at one end to stow the air mat and the other end unfolds to become the built-in pump.

The Airstream™ Pumpsack can be inflated with a single breath and takes just two or three cycles to fill our mats. Not only is it faster than inflation by mouth, but there is minimal breath condensation entering the mat and it eliminates dizziness from blowing the mat up directly by mouth.

The Airstream™ Pumpsack is also compatible with Sea to Summit's smaller multifunction valve, which is now featured on the updated Aeros pillow range, along with the Air Seats.

ASTM F3340-18 R-VALUE TESTING

To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value.

A laboratory-tested R-value is the only way to measure resistance to heat loss. Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats.

Since January 1, 2020, we are using the new industry standard ASTM F3340-18 test to provide R-Values for our mats.

In some mats, the new test protocol means changes to previously published R-Values. Where values do change, it doesn’t signify a drop or increase in warmth—it simply means they have been tested using a slightly different scale. The packaging may still carry the pre-2020 R-Value.

Thermolite® HL-1

Thermolite® HL-1 is part of the family of Thermolite® materials used in Sea to Summit sleeping bags, sleeping bag liners and sleeping mats. HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ of our sleeping mats to prevent convective heat loss from your warm body to the cold ground.
