Super warm mat with Downmat Technology(TM). Filled with goose down (700 cuin), this air mattress is 3x warmer than other mattresses of the same weight. The thick air padding is super comfortable. Internal foam strips on the head and foot sides prevent the down from being blown out through the valves or from migrating between the channels. Two fabric loops are attached to the headboard for tying the stuff sack as a pillow. The longitudinally oriented air chambers support the body and lead to more sleeping comfort. Exped&';s exclusive side chambers center and keep the sleeper on the mat. Exped calculates, reduces and offsets all CO2 from the manufacture and transport of this product (myclimate.org/01-20-799878). Thanks to recycled polyester, no plastic ends up in landfills. Less water, energy and carbon are used in production. Including Schnozzel Pumpbag: Quick, moisture-free inflation of the mat without lung power! Recycled 75 D/170 D polyester, Oeko-TexA(R) 100 certified, 700 cuin RDS down.
