The Therm-A-Rest NeoAir XLite Ultralight Inflatable Air Mattress for three-season backpacking, mountaineering, and camping is the ultimate minimalist’s expedition sleeping pad. Offering maximum warmth for the weight, it's designed specifically for adding a padded layer of warmth and insulation between sleeping bag and ground in alpine conditions. Proprietary reflective ThermaCapture technology traps radiant heat within the mat, while the Triangular Core Matrix minimizes heat loss during sleep. With an R-value of 3.2, it’s ideal for sleeping outside in spring, summer, and fall (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). Baffled internal structure provides support and comfort in a 2.5-inch inflated mattress, for a restful night in the backcountry. Inflates easily in less than two minutes by blowing into the valve, for quick setup in a bivy or a tent. The Therm-A-Rest NeoAir XLite sleeping pad is perfect for lightweight expeditions thanks to its innovative tapered design and materials, which eliminate bulk, making it possible to pack the ground pad to the size of a one-liter water bottle. Available in three sizes: Small measures 47x20x2.5 inches inflated, packs to 9x3.3 inches, and weighs 8 ounces; Regular measures 72x20x2.5 inches inflated, packs to 9x4 inches, and weighs 12 ounces; Large measures 77x25x2.5 inflated, packs to 11x4.5 inches, and weighs 16 ounces. Stuff sack and repair kit included. Made in the USA.

One of the most common complaints I hear and read about inflatable pads is the old cold butt syndrome where someone goes to sleep with the pad just fine but they wake in the morning because they think it deflated overnight. Usually this happens in colder conditions and usually it never deflated at all. The problem is pretty simple although can get complex. Using the formula (pressureA x volumeA)/temperatureA = (pressureB x volumeB)/temperatureB with pressure being constant since your body weight creates the bulk of the pressure you can predict the volume of air in the pad at varying temperatures. If you blow into it with your body temperature air and assuming it cools a little as you blow in and accounting for the cooling of the air in the pad due to conduction with the ground you can determine volume. Let's say the air in the pad is down to 70F when you lay down but it gets down to 50F at the coldest time the volume will decrease by almost 30%. To avoid the cold butt you have to blow the coolest air into it as you can (via a pump or stuff sack pump), blow more into it when you think it's full (increasing the initial pressure value), or blow it up when you set up camp then blow more into it just before bed time.
Happy hiking to you!
Pros: Lightweight, compact, and you'll never sleep on the actual ground
Cons: LOUD, crinkles with every move. If your tent-mate doesn't have the same pad you'll probably hear some complaints. It's also a but narrow, I would have loved another 2 inches on the sides.
