The AirCore is RidgeLine's top-selling 3-season sleeping pad — a self-inflating, insulated air pad that strikes the balance between packable comfort and genuine thermal insulation. The R-4.2 rating makes it suitable for three-season use down to around 20°F when paired with an appropriate sleeping bag.
The 80-gram synthetic fill inside the pad's air chambers distributes warmth across the full pad surface, eliminating the cold zones that affect simpler non-insulated inflatables. A flat-valve inflation system (3 to 5 breath inflations) gets you from packed to sleeping in under 90 seconds. The textured surface grips sleeping bag bottoms and prevents sliding on smooth tent floors.
