The Sea to Summit UltraLight utilizes the company's new Air Sprung Cell design and is a great choice for warm weather trips. This pad is super lightweight and packs down to the size of a couple pop cans. When comparing full sized pads, this one is the most compressible and the second lightest of any that we've tested. The unique air valve was the best of any sleeping pad we've seen allowing for easy inflation and instant deflation. If you want an inflatable pad for ultralight backpacking, this is an excellent pick and narrowly ceded our Top Pick for Ultralight award to the Therm-a-Rest NeoAir XLite pad because the XLite is much warmer and a tad lighter. The UltraLight is an excellent pad for summer backpacking or any instance where you want a comfortable pad without sacrificing weight or pack space. It is also a super great value because it retails for just $100 making it a full $30 less expensive than the higher scoring XLite. The UltraLight has many of the same features as the Sea to Summit Comfort Light Insulated, which weighs 8 ounces more, costs $70 more, but is much warmer.
This pad now comes with an Air Stream Dry Sack Pump, which acts a stuff sack, a pump, and a dry sack! With a few quick puffs of air into the sack, you can inflate this pad without getting dizzy. See how it works in this instructional video.
