The Sea To Summit Ether Light XR Insulated Air Sleeping Mat - Small is a lightweight, insulated and extra thick air mattress-like sleeping mat for hiking, thru-hiking and bikepacking. The Small version measures 168 × 55 centimeters, weighs approximately 445 grams and is suitable for users with a body height of up to approximately 168 centimeters.
The 10-centimeter thick construction provides plenty of space between your body and the ground. Air Sprung Cells individually shape themselves to your body's movements, creating a stable and flexible sleeping surface, whether you sleep on your back, stomach or side.
ThermalCore insulation gives the sleeping pad an ASTM-tested R-value of 4.1, making it suitable for spring, summer, and fall, as well as cooler nights when ground frost may occur.
The R-value indicates how effectively the base prevents heat loss to the ground. The actual sleeping comfort is also affected by sleeping bag, clothing, wind, humidity, ground temperature and individual cold tolerance. For winter trips and severe cold, the base should be supplemented with a foam plastic base or replaced by a model with a higher R-value, such as Ether Light XR Pro.
ThermalCore consists of a suspended, heat-reflecting TRM layer inside the sleeping pad. The material reflects back some of the body heat and limits air movement inside the structure.
The reflective material is softer and quieter than traditional insulation films. The construction therefore provides a good balance between insulation, weight and packing volume without the sleeping pad becoming unnecessarily noisy.
The Air Sprung Cell™ construction consists of many interconnected air cells that act much like individual springs. The cells adapt to the body and distribute pressure across the sleeping surface.
The generous thickness is especially appreciated by side sleepers, as it reduces the risk of hips and shoulders being pressed down onto the ground. The firmness can be easily adjusted by releasing small amounts of air via the XPRESS valve.
The Small version's length of 168 centimeters helps keep weight and pack volume down. It's suitable for shorter users and weight-conscious hikers who don't need a full-length base.
The base has a tapered mummy shape that saves material and space in the tent. Check the length before purchasing – users taller than approximately 168 centimeters should normally choose Regular or Large.
The storage bag also functions as an Airstream™ pump bag. It is filled with air and connected to the valve, allowing the mat to be inflated with just a few pumps. This method also reduces the amount of moisture from exhaled air that ends up inside the mat.
The XPRESS valve provides high air flow and has separate functions for inflation, fine-tuning and rapid deflation. When the valve is fully opened, air is quickly released before rolling up.
The outer fabric is made of lightweight and durable 30D/40D nylon with TPU lamination. Reinforced welds contribute to better durability and an airtight construction.
Included PillowLock™ attachment points can be placed on the sleeping pad to hold a compatible Sea to Summit Aeros pillow in place. Pillow not included.

Unroll the sleeping pad and open the XPRESS valve to the inflation position. Connect the storage bag's integrated pump bag and inflate the pad until it is relatively firm. Then lie down on the pad and use the valve's fine adjustment to release air until you get the support you want.
Check the ground and remove rocks, branches and other sharp objects before laying out the ground. A footprint or thin protective ground can reduce wear when used outside the tent.
Wipe the mattress with a soft cloth, lukewarm water and a mild detergent. Do not immerse the valve in water and do not use a washing machine or dryer.
Allow the base and its interior to dry thoroughly before long-term storage, especially if it has been inflated by mouth. Store dry with the valve open and avoid sharp objects, open flames, strong heat and prolonged exposure to direct sunlight.
