Size Guide

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 14ºF means a man should be comfortable down to air temperatures of 14ºF. The same bag will also have a Comfort limit, in the realm of 27°F, so a woman would be comfortable down to an air temperature of 27ºF. 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

Sleeping well when you are backpacking requires that you sleep comfortably. The Comfort Light™ Insulated sleeping mat uses Air Sprung Cell™ technology and a hybrid matrix of offset cells to provide excellent stability and amazing comfort. There is a double layer of cells in the torso for increased comfort and warmth, and a single layer of cells in the head and legs to reduce the weight. Thermolite® and Exkin Platinum® are used to optimize heat retention and the multi-function valve allows simple inflation, deflation and the ability to easily fine-tune your personal comfort level.

The uprated 30D / 40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability

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

Technical Features

Hybrid 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 Light series of mats has an internal layer of 40 D Nylon in the torso section. This allows the welds of the lower and upper cells to be offset, resulting in a greater number of cells in this area for greater support and insulation. The cells in the head and leg sections of the mat do not have this internal layer, which saves overall weight. This hybrid construction (two different weld patterns) may be the perfect option for an end user looking for more comfort and insulation without adding to much weight.

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.
