Nemo Equipment Inc. added PrimaLoft insulation to one of its tiniest pads so you can sleep soundlessly on the Astro Insulated Sleeping Pad when you backpack in colder weather. The durable yet plush polyester shell is tear-resistant, quiet, and very comfortable. The lateral baffles inflate up to 2. 5 inches above the bumpy ground so you can sleep without a stone pressing up against your back. This pad compresses down smaller than a jet boil stove, and its stuff sack makes sure the pad doesn't bulk up your pack so you can bring as many warm layers as possible. Self-inflate this pad, or use the Disco Pad Pump (sold separately).
