The Good

  • Large surface area
  • Easy to use
  • Flexible and durable

The Bad

  • Only 2" thick
  • Dimples compromised insulation
THE VERDICT

The Sea to Summit UltraLight Insulated Mat is average weight and warmth, but has impressive durability on all surfaces. The dimpled cells were not optimal for side sleepers and took away from the insulating properties.

FULL REVIEW

Comfort
The Sea to Summit mat is 2 inches thick, leaving not much room between the hip and the ground for a side sleeper. The large width of the mat is more comfortable when moving around and great if the tent allows for it. The dimpled cells are comfortable, as they create flexibility, however lack in creating a firm, even surface.

Weight
At 18.9oz on our scale, the UltraLight Mat is just above average weight, which may be because of its more durable fabric. However, it still packs down to a relatively small package. The packed shape is slightly longer than the comparable mats.

Warmth
The UltraLight Mat is rated quite warm at 3.3 R value. During testing, we found it to not live up to it’s rating because its 2 inch height did not leave much room between the body and the ground. However, the pad was used in a very wet Pacific Northwest night and kept the tester above the water and dry.

Durability
The 40D ripstop proved to be tough and durable on all surfaces even when kneeling directly on the pad. The nylon material proved to be extremely durable and resistant to abrasive and sharp surfaces. Note: The D, standing for Denier, essentially means the weight of the fabric (or thickness of thread used).

Ease of Use
The UltraLight Mat works best with a pump bag, which filled the mat in less than two minutes with around six pump bag fills. The multi-functional valve actually has 3 functions – to inflate, to deflate (rapidly), and  you can also depress the orange button when it’s in inflate mode, to fine tune the inflation level.
