Product Info

With a trimmed down profile and ultralight 40D nylon fabric, the Sea to Summit UltraLight Insulated Sleeping Pad is seriously light. It weighs in just over a pound, but still provides plenty of insulation for an R-value of 3.1. That kind of weight-to-warmth ratio makes it a favorite of long distance hikers who need the most bang for their buck in the weight department.

Product Details


40D Nylon Face Fabric


Thermolite HL-1HL-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™ to prevent convective heat loss from your warm body to the cold ground.


Small66" x 21.5" x 2"

Regular72" x 21.5" x 2"

Large78" x 25" x 2"


Integrated Airstream PumpsackThe 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.

Single Layer Air Sprung CellsInspired by the hundreds of springs found in a modern pocket sprung mattress,the hundreds of small interconnected chambers perfectly support your weight and conform to your body contours. The Ultra Light range has a single layer of medium resolution cells to give you the lightest and smallest packed volume mat without compromising on Sea to Summit's Air Sprung Cell comfort.

Multi-function Valve for Fast and Easy Inflation, Deflation and Fine Tuning of Air Pressure.

IncludesQuality stuff sack which doubles as a pump, a repair kit containing six self-adhesive patches for repairing punctures in the field, and two spare silicone one-way valve inserts.

Anti-Microbial Treatment Added to TPU LaminationTo prevent delamination/mold issues caused by moist air trapped inside the mat.
