The opinion of Aventure Nordique

The Insulated Air Core Ultra by Big Agnes is an insulated air mattress for 4-season use. This model is designed to be used up to a comfort temperature of -9°C. To achieve these thermal performances, the tubes are equipped with a Primaloft synthetic fibre filling. R-Value 4.5 according to the international standard.

This air mattress has a double flat valve for inflation and deflation. The inflation valve has a non-return valve. To deflate the mattress, simply open the valve and the effect is immediate! It comes with a pump bag that makes inflation easier and avoids sending humid air into the tubes.

The construction and structure provides a stable and smooth sleeping surface. At the ends, the bulkier tubes keep you in the middle of the mattress.
