Pros & Cons

Reasons to buy:

User Reviews

  • Easy to pack down into the stuff sack for transportation.
  • Rolls up tightly for easy compression.
  • Very lightweight.
  • Easy to set up and break down, allowing for extra efficiency when backpacking.
  • The shape is wide and has a minimal taper, which aids in keeping you centered on the pad during the night.

Expert Reviews

  • Very lightweight and compact.
  • Easy to inflate after the first time.
  • Dual-dial setup makes inflation easier and quicker.
  • Thickness between your body and the ground is adequate to not feel debris.
  • Good warmth-to-weight ratio.
  • Packs down small and transports easily.
  • Easy deflation due to the dual-valve.
  • One of the most compressible pads in this space.
  • Second-lightest pad in this space.
  • The air valve is the easiest for inflation and deflation.
  • Wide enough for most peoples’ shoulders to fit comfortably.
  • Affordable.
  • Only the Thermarest NeoAir is lighter but that pad has some downsides that this one doesn’t have.

Reasons NOT to buy:

User Reviews

  • Less durable than other options on the market.
  • The movement of the pad against the floor of the tent can cause some noise.
  • Small window of inflation between being overly-blown up, and too deflated.
  • The NeoAir is lighter.
  • Some reports of limited durability, like deflating or sanitation issues.

Expert Reviews

  • Might not be durable enough and warm enough for camping mostly in cold climates or on snow.
  • Dimples when fully inflated, and can trap some debris on the top.
  • Slightly heavier than some other models on the market.
  • The dots on the mat collect dirt easily.
  • Not the most comfortable option due to being a bit thinner and ‘bumpy’ due to the dots.
  • Doesn’t provide enough insulation, and the R-value is just 3.3, which is fairly low.
  • Some durability issues due to being a newer pad and not having enough other reviews and tests on the market. The pad deflated on the first day in one test.
  • The noise wouldn’t wake most people up at night, but the mat does make some noise while rolling around when sleeping.


The Sea to Summit UltraLight Insulated Mat is a very lightweight pad that is easily packable, supportive, and comfortable. The fairly low insulating value does not make this the best option for colder climates, but the compactness and feather weight make this a top choice for summer backpacking.
