The Women’s Ultralight Insulated Air Sleeping Mat saves weight because it's narrower at the shoulders, yet wider at the hips and knees for greater comfort no matter what position you sleep in. There is also extra Thermolite® insulation to provide tested three-season warmth for women backpackers.
The uprated 30D/40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.
DESIGNED FOR WOMEN
Shaped for comfort
Narrower at the shoulders, but wider between the hips and knees. This shape significantly enhances comfort for those who sleep in a figure-4 position (or on their sides or stomach) by giving them the room they need to move while they sleep.
Air Sprung Cells provide support
Air Sprung Cells provide a stable, supportive sleeping surface. Hundreds of individual air-filled springs (or ‘cells’) provide the kind of support you may be used to from a high-quality pocket sprung mattress. All sleepers – but particularly those who need hip and back support – will benefit from the stability that an Air Sprung Cell pad offers.
Air Sprung Cell pads are quieter than air pads which use a reflective film in their construction. Less noise throughout the night means a better night’s sleep, night after night – Sea to Summit pads use stronger materials and more reliable technologies than other pads. Women’s Air Sprung Cell pads also feature more lofting insulation than the unisex version.
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 Ultra Light range has a single layer of medium resolution cells to give you the lightest and smallest packed volume mat without compromising on Sea to Summit's Air Sprung Cell comfort.
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.
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 2020 we have used the industry standard ASTM F3340-18 test to provide R-Values for our mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.
The uprated high tensile yarn, high thread count 30/40D ripstop nylon face fabric of our Air Sprung Cell™ sleeping mats is quiet, light and extremely durable. On the inside, we apply a bright white TPU to make the fabric airtight and weldable - it also contains a permanent antimicrobial treatment to ensure mold will not form on the inside of the mat. These characteristics combine to form the strongest, most durable air mat fabric available. On the outside, we apply a thin proprietary coating to reduce the slipperiness of the surface, increase water resistance, and aid puncture repair with the included self-adhesive patches.

Frequently Asked questions
Really comfortable at this thickness?
Yes. Thickness isn't the key factor for sleeping pad comfort – the number of points of suspension is. Our air sprung cell sleeping pads support your body weight with hundreds of individually air-filled springs.
Easy to inflate?
Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly inflate the sleeping pad. This means no dizziness for you, and practically no condensation moisture inside the pad.
Noisy when I shift around in my sleep?
No. The reflective material (Exkin Platinum®) and the outer laminate material are both very quiet. Your tent buddy will thank you in the morning.
Is the Women's UltraLight Insulated warm enough for three-season camping?
Yes. Two types of insulation prevent radiant and convective heat loss. The mats have a tested R-Value of 3.5, and the lack of internal air movement means minimal loss of warmth compared to other designs.
