The NeoAir All Season SV mats are exceptionally compact, light and rugged four-season mattress with ultra-fast inflation/deflation.

Thermarest says:

Our cult favourite, four season, go-anywhere air mattress just got better. Now sporting the game-changing SpeedValve™, our rugged All Season inflates up to three times faster and deflates instantly. Multiple layers of ThermaCapture™ technology make it one of our warmest and most versatile NeoAir mattresses. We also added a Regular Wide size to maximize sleep surface without adding length. Stuff sack and repair kit included.

NeoAir™ Mattresses

In this patent-pending application, we vary the location and number of ThermaCapture layers within each NeoAir mattress to meet specific warmth targets. Combined with Triangular Core Matrix construction, a single ThermaCapture layer can boost warmth by up to 50% and creates the unmatched warmth-to-weight ratios offered by a NeoAir mattress

ThermaCapture

ThermaCapture Radiant Heat Technology is a proprietary reflective coating that we apply to a range of surfaces. By reflecting radiant heat back to your body that is otherwise lost, this extremely lightweight coating turns that surface into a very efficient heat reflector, amplifying warmth without the excess weight or bulk of added, conventional insulating materials.

There are a range of models of Thermarest's NeoAir mats available, and each one is available in a range of sizes. They are all very light insulated airbeds, so they are very comfortable compared to other types of mat and they have very small pack sizes. Which model is the right one for you will depend on the level of comfort, durability, insulation value, weight and amount you want to pay.

Even the NeoAir models that offer the least insulation are warm enough for three season use, although a warmer mat means a lighter sleeping bag can be used. The All Season mats are among the warmest so you could use them all the year round, although there are better ones for camping on snow.

The 'All Season' models are rectangular, which gives you more mat to move around on, and they have durable face fabrics with greater puncture resistance and better long term durability than the super light mats such as the Xlite.

The 'All Season' models now feature the integrated SpeedValve which is a remarkable way of inflating your mat with negligible effort - watch the video - you'll be amazed.

In summary the NeoAir All Season mats are mid range in terms of their weight, but for that you get supreme comfort, robust face fabrics, a high insulation value and effortless inflation.
