The opinion of Aventure Nordique

The Neoair Uberlite is the lightest and most compact mattress in the Thermarest range. It beats all records and is the lightest inflatable sleeping system in the world!

It is an insulated air mattress, dedicated to a 3 seasons use. It is designed for campers in search of a minimalist mattress, the Uberlite having almost no impact of weight and volume in the backpack.

To achieve this performance in terms of weight (250 g in size 183 cm) and comfort (6.4 cm thick), Thermarest still uses the Triangular Core Matrix technology which minimizes heat loss by convection offering an R-Value of 2.3, calculated with the new ASTM F3340-18 standard.

The Uberlite has a light and thin 15-denier nylon fabric. Materials that require very careful use!

Compared to a NeoAir Xlite mattress, the Uberlite is not equipped with ThermaCapture reflective layers and has a fabric that is half as thick, while maintaining the same thickness. It is therefore less insulated than the Xlite but lighter.

It is equipped with the latest Thermarest valve. The WingLock valve allows you to inflate and deflate faster. It has a non-return valve that prevents air from escaping during inflation. The mattress is supplied with a storage box and a pump bag that prevents blowing moisture into the mattress.
