Dual Layer Air Sprung Cells – The Comfort Plus series has an internal layer of 40 Denier Nylon dividing the mat into an upper and a lower chamber. This allows the welds of the lower and upper cells to be offset throughout the entire mat, resulting in the greatest possible support and insulation, and a unique ability to fine-tune comfort. When on uneven terrain the bottom layer of the mat can be inflated to a high pressure as a barrier. The upper layer can then be adjusted - using the fine tune valve – for more comfort and softness.

Integrated Airstream Pumpsack – The Airstream™ Pumpsack is Sea to Summit's big volume mattress pump. 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 the mat. 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.

Pillow Lock™ System – 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.
