The opinion of Aventure Nordique
The Granby Insulated Sleeping Pad from Sierra Designs is a mattress with 100% polyester insulation. Its R-value of 2.1 allows for 2 season use. The fabric is a 20 denier nylon to keep the mattress light.
It is equipped with a one-way valve for efficient inflation and deflation. Its atypical relief allows a thickness of 7.5 centimetres for good comfort, while offering a correct weight. Rather than traditional horizontal or vertical tubes, the Granby Insulated Sleeping Pad is equipped with a multitude of small chambers, connected at the corners by a channel. This provides more stability and prevents air from being pushed to one side or the other when turning over.
Available in one size, it measures 183 centimetres long by 51 centimetres wide. It is supplied with a patch kit and a large opening storage bag. The latter allows for quick and easy storage.
