The opinion of Aventure Nordique
The Circle Back Insulated from Big Agnes is a mattress with a cover.
The inflatable mattress is rectangular in shape and 10 cm thick, with a honeycomb construction for optimum comfort. Inside, a reflective film provides a first level of insulation. It has a single valve for inflation and deflation, with a non-return valve for fine pressure adjustments.
The polyester cover is extremely soft. In addition to the silky contact it offers with the mattress, it reduces the noise usually associated with air mattresses. It's filled with FireLine Eco fiber for a high level of insulation. It is removable and machine-washable.
Its R-Value insulation index is 4.7, according to international standard ASTM F3340-18, so it can be used in all seasons.
