The opinion of Aventure Nordique
The Exped Ultra 1R Duo is a lightweight, mattress in mummy form. It has very high performance characteristics. For 2 persons.
- Insulation: uninsulated Airmat Technology, it is a mattress for temperatures above 10°C, with an R-Value of 1.3, ASTM F3340-18 standard.
Comfortable: in size M, you have a thickness of 7 cm with a maximum width of 105 cm and a length of 183 cm. The flanges on the edges of the mattress are higher than the others, which prevents the mattress from slipping off. - Lightness: The materials used (20 denier recycled polyester) and the mummy shape (narrower at the feet) allow Exped to offer a very light mattress: 700 grams, which is an achievement considering the comfort it provides and the thermal performance.
The Ultra 1R Duo has two flat valves that do not protrude from the mattress, one for inflation with a non-return valve and one for deflation. It is sold with the Schnozzel Pumpbag UL to make inflation easier and to avoid sending wet air into the mattress structure.
The mummy shape is particularly interesting:
- To save weight.
