Jump to: Our Verdict / Features / Specifications

Ultralight and compact, this exceptionally comfortable mat is ideal when light and fast is your aim and getting a great night’s sleep is essential for the next day’s adventure.

Sea to Summit says: 

The Ultralight sleeping mat range has a single layer of medium resolution Air Sprung Cells™ to give you the lightest and smallest packed-volume mat without compromising comfort. These mats are ideal when going light and fast is your aim and getting a great night’s sleep is essential for the next day’s adventure. All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.

Air Stream Pumpsack now integrated into the included stuff sack.

Our Verdict

The air sprung cells are the core technology of this mat, allowing you to have a comfortable nights sleep. Instead of the typical baffled construction, these sleeping mats are constructed using a matrix of air cells that move independently to conform to your body’s shape without affecting adjacent cells. Translated to backpacker-speak, that means you don’t flatten out spots under, say, your hipbones or shoulders.

The Sea to Summit UltraLight range is not as warm as the comfort Light range however it is lighter and has a much smaller pack size.

Now comes packaged with a Sea to Summit Airstream stuff sack.
