Description
If you're looking for a lightweight sleeping pad but don't want to compromise on comfort, durability, insulation or ease of use, look no further than the Ultralight Insulated Air Sleeping Mat. The Air Sprung Cell design delivers stability and support, while our lamination and weld quality set a new standard for reliability. What's more, Thermolite® and Exkin Platinum® insulation deliver the warmth of an ASTM standard R-Value of 3.1 - just perfect for late spring through to early fall camping.
Design Details
Technical Features
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.
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.

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.
Did you know that you can turn the Stuff Sack inside out and have a pump for your Sea to Summit pillow? Try it out!
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.
Does the insulation in the UltraLight Insulated protect me from the cold air and ground temperatures?
Yes. Two types of insulation prevent radiant and convective heat loss. The mats have a tested R-Value of 3.1, and the lack of internal air movement means minimal loss of warmth compared to other designs.
