Rab Ionosphere 5 Sleeping Pad

The Rab Ionosphere 5 is a winter-rated insulated air pad with an R-value of 4.8 — high enough to cover four-season use and genuinely cold nights where a typical 3-season pad around R-3 falls short. Warmth comes from a combination of Stratus R synthetic insulation and Rab's TILT reflective film, which bounces body heat back up toward the sleeper. The Long Wide version (196×64 cm) at 8 cm thick offers above-average room and cushioning, which shows up in the 810 g weight — this pad is built for winter trips and cold-weather trekking rather than lightweight summer use. A 20D top fabric paired with 30D on the bottom, horizontal baffles, and two flat, low-profile valves are the kind of details you'd expect on a premium winter pad. The package includes a pump sack, stuff sack, and repair kit, and the materials are partly recycled and PFC-free. Packed down, it measures 28×12 cm — a reasonable trade-off between pack volume and the sleeping comfort this level of thickness and insulation delivers in cold conditions.
