At four inches thick, the Women's Ether Light XT Insulated Air Sleeping Mat brings Air Sprung Cell comfort to the realm of thicker air sleeping pads. Featuring additional Thermolite® insulation (compared to the unisex model), this pad provides three-season warmth for women backpackers. The XT Air-Sprung Cells are constructed using loops of a strong, flexible material to provide a plush sleeping experience. The uprated 30D/40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.
The sleeping pad shape is narrower at the shoulders and wider between the hips and the knees. This guarantees greater comfort regardless of sleeping position, and perfectly complements Sea to Summit’s women’s sleeping bag range.
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 springs of a modern pocket sprung mattress, dozens of interconnected chambers (called Air Sprung Cells™) perfectly support your weight and conform to your body contours. The Ether Light range uses loops of TPU material to connect the top and bottom welds. This produces a thicker cell to give you a plush sleeping experience 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.
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.
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.
Sea to Summit Women’s Specific Sleeping Pads:
Built differently from the ground up, to provide women adventurers with the best possible sleep.
Both Air Sprung Cell and Self-Inflating mats have a shape that is narrower at the shoulder, then widest between the hips and knees to permit a natural side or ‘figure four’ sleeping position. Air Sprung Cell pads have more Thermolite® insulation than their Unisex counterparts. Self-Inflating pads have smaller-dimensioned Delta Cores in the hip and foot sections to create extra Comfort and Warmth Zones.
Sea to Summit Women’s Specific Sleeping Bags:
Engineered differently than Unisex models, to provide women adventurers with the best possible sleep.
They have a shape that is narrower at the shoulder, then widest between the hips and knees to permit a natural side or ‘figure four’ sleeping position. Women’s specific body mapping deploys insulation for warmth where it is most needed. Additionally, the Journey and Altitude down bags have a layer of Thermolite synthetic insulation in the footbox to warm your feet more quickly.
Journey, Altitude, and Venture can be zipped into many Sea to Summit Unisex sleeping bags.
