Sea to Summit Ultralight Self Inflating Mat

Technologies and manufacturing processes

• DELTA CORE-V

  For our lighter SI air mat models, we have removed 20% of the weight and volume of the PU foam by using our vertical Delta Core-V process. We use sophisticated pressure mapping data that serves as a blueprint for our distinctive graduated core pattern. Where extra warmth and support is needed for the body contact areas - shoulders, hips and feet - the core holes are smaller. In the less critical areas, we've removed more foam to minimize weight and pack size. Delta Core-V technology is used in our Ultra Light SI and Camp Mat SI models.

• MULTI-FUNCTION VALVE

  To make inflating and deflating the air mattresses easier, Sea to Summit has developed the multifunction valve. This valve features an inflation port with a one-way valve that prevents air loss before the valve closes, a quick deflation port and a button for fine-tuning comfort - all in one compact, low-profile unit. It has also been designed to connect easily to a pump to simplify inflation.

• EXTRUSION LAMINATION

  Extrusion lamination is widely used in the medical and aerospace industries, but Sea to Summit was the first to use it for outdoor products. Liquid thermoplastic urethane is applied to the outer material through an extrusion head, where it bonds permanently. The result is: Sea to Summit sleeping mats are more reliable and durable.

• PILLOW LOCK SYSTEM

  The Pillow Lock System consists of self-adhesive Velcro patches that are supplied with all Sea to Summit sleeping mats (from spring 2019). Attached to your sleeping mat, these patches secure your pillow and prevent it from slipping - yet won't catch on clothing or other lightweight fabrics. All Sea to Summit Pillows (from spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock compatible by adding an Aeros pillowcase.
