The Women’s Delta Core-V™ concept is simple: remove enough foam to cut down weight, leave enough foam to ensure comfort and warmth. The Women’s UltraLight Self-Inflating Sleeping Mat is constructed with Comfort Warmth Zones in the hip foot and torso areas to provide extra support and insulation for the woman backpacker who wants to keep her load light.
DESIGNED FOR WOMEN
Shaped for comfort
Wider through the shoulders and hips than a traditional sleeping pad, the shape enhances comfort for those who sleep in a figure-4 position or move frequently through night making it easier to stay on the wider surface area throughout the night.
Maximum comfort with Delta Core V Technology
The Women’s Specific sleeping pads are constructed to provide the most comfort while minimizing bulk and weight. Our Women’s Delta Core V technology leaves foam intact in the hip, foot and torso areas to create extra-comfort and support.
Warmth throughout the night
Our Women’s Delta Core V technology leaves foam also provides additional warmth in the areas where heat is typically lost, like the feet. This thoughtful construction results in a noticeably warmer sleeping pad.
To make inflation and deflation of its air mats easier, Sea to Summit developed the multi-function valve. This valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort - all in one compact, low profile unit. It has also been designed to allow easy attachment of a pump, for simpler inflation.
The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019). Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics. All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.
The Women’s Delta Core-V™ system uses a revised pattern of Delta-shaped vertical cores to leave foam intact in the hip, foot and torso areas to create extra-comfort / extra warmth zones. The coring technology results in a smaller packed size and lighter weight than conventional self-inflating mats while providing extra support and insulation where women need it most. The Women’s Delta Core-V™ technique is used in our Women’s UltraLight SI models.

Frequently Asked questions
Is the Women's Ultralight Self-Inflating Sleeping Pad warm enough for three-season use?
Not really. This self-inflating sleeping pad has a tested R-Value of 2.6, which only provides enough insulation for the moderate temperatures of late spring to early fall.
How is this self-inflating sleeping pad different from other lightweight sleeping pads?
This sleeping pad features Women’s Vertical Delta Coring Technology, which reduces the weight and packed volume of the foam by 20%, while providing additional comfort and warmth zones for hips and feet.
Is the packed-size compact enough for backpacking?
Yes! This sleeping pad will fit easily into a 55+ liter backpack. However, performance-oriented backpackers may prefer an Air Sprung Cell pad.
